I recently completed a PCM 40 series transmission to PCM 80 series transmission swap in my 2012 SAN 210 TE. I took some pictures along the way and I am going to post them for people to use my experience to make theirs a little easier. I will say overall if you have the tools handy it was not that big of a job in my opinion, but I did run into some speed bumps along the way. Backstory, I bought this boat used from a dealer in South Carolina. Within a few weeks the transmission started slipping due to water intrusion. My mistake was I checked the fluids over before test run and not after. Once I got into the replacement I found evidence that either they or the owner before me knew of the issues. However, I bought it so I fixed it. I am not bashing them, but rather just giving the story of how I got here. LOL So instead of rebuilding the current 40 series transmission I decided to completely swap to the 80 series. So it began...

First, I added an Eye-bolt to the ceiling of my garage to utilize for minimal lifting of the rear of the engine. Second, I cut blocks to go under the hoisting rings on either side of the motor to support the weight of the motor once I removed the rear mounts.

Then I removed the prop. This was my first speed bump. The prop had not been removed in a number of years and had almost fused with the shaft. I tried multiple methods that worked for me in the past including heat to no avail. I broke down and bought a ACME C-Clamp style puller to overcome this speed bump, so I now have one in my tool kit. Once this was complete I moved inside the boat to clear room to work. I removed the floor to access the V-drive and make more room for removal.

Next, I went through the rear hatch to remove starter, Oil filter w/hanger, wires for the sender, and the shift cable.

At this point I removed the inlet and outlet water hoses from the v-drive and bolts from the coupler. I then attempted to un-mate the couplers.

Well… This was speed bump 2… they had been married a long time and did not want to be separated either. Even after I broke the coupling mate up the shaft side coupler did not want to come off the shaft. With the close proximity to the fuel tank I was hesitant about introducing heat with a torch, so I tried multiple ways to get it off. Even bent a harmonic balancer puller trying to get this thing off. After seeing a video of a puller online I purchased it since it utilized four bolts to pull more evenly. However, it was going to be about 5 days for delivery. So I decided to remove the shaft through the floor with the coupler still attached. In order to accomplish this I had to loosen the brackets for the forward ballasts and the fuel tank brackets to slide the fuel tank back to get enough clearance to remove the shaft with coupler.

Once the shaft was removed I supported the rear of the motor utilizing straps to the eyebolt and wood blocks under the hoist rings on either side.

Now that it was secure I could start the removal process. I removed the shift linkage bracket that happened to be held in place by two of the nuts that held the V-drive to the transmission. Then finished removing the 8 nuts from the rest of the studs that attached the v-drive to the tranmssion.

I move back to the forward facing part of the v-drive and removed the intake water hoses for the ballast make more room for the removal process.

At this point I supported the v-drive with wood blocks and I removed the four bolts that attach the V-drive to the mount (2 on either side).

Remove the v-drive and set out of the way.

After the v-drive was removed I figured the transmission would not fit through the v-drive mount so I removed the 4 bolts connecting the mount to the stringer brackets and moved it out of the way. Once the v-drive mount was out of the way I removed the four main transmission mount bolts out of the mounts and loosened them to swing them out of the way. In the pic below you can see the top bolt, but two are behind the exhaust and the last one is under the one viewable in the picture. Warning: Now all weight of the motor on that side will be on your blocks and straps.

Now that the engine is supported I used the wood blocks to support the transmission so I could remove the four main transmission to bell housing bolts. At this point I removed the transmission and got it out of the way.

Now you have a clear view into your bell housing and can see the damper plate. Now we are ready to remove the bell housing. The first thing I did was removed the smaller dust shield bolts along the bottom of the bell housing. I believe there were 6 in total. Then removed the grounding wires and used two nuts to remove the grounding studs on both sides of the block. There was one bolt on the very top of the bell housing and then two hidden bolts. These took a minute to fins and I had to research to find them. Thanks to a person that posted about GM blocks having a hidden bolt I was able to find the one identified in the starter hole. There is a plate behind the exhaust that covered a similar hole to the starter hole with a hidden bolt. The hidden bolts in the holes were twelve point bolts if you start trying to pull those out.

Now, you can remove the bell housing to access the damper plate. Remove the 6 bolts around the exterior of the damper plate to remove it from the flywheel.

After the damper plate is removed I had clear visibility of the flywheel and how much rust was on it. With the amount of rust on the flywheel I took the opportunity to clean off some of the rust.

Once the flywheel I began the installation process starting with the installation of the new damper plate.

Reinstalled the bell housing and dust shield. Installed the one top bolt, the two grounding studs, and the two hidden bolts that fasten the bell housing to the block. Once this was complete I replaced the cover over the whole of the second hidden bolt that is behind the exhaust.

Removed the new transmission out of the box and prepare it to install by putting all of the necessary fittings in to install the new transmission cooler.

Now I took advantage of the eye-bolt and used a small strap to help me lift the transmission in place. Installed the four main bolts that were holding the transmission in place to the bell housing.

I took advantage of the open space and installed the hoses for the transmission cooler and then the v-drive mount. I also loosely installed the transmission mounts to help support the transmission, but these will have to be uninstalled for the alignment part of the installation.

I then took the time to clean up the v-drive coupler and remove a majority of the rust (I find out later that it was not enough though). I use the eye-bolt and a small strap to once again help with the installation process. I had to remove the studs from the old transmission to make this installation (once again using the two nut process for removal).

With the two major components in I went ahead and installed the new 12” transmission cooler and lines in the place of the old 5-6 inch one that came stock. I was able to use the same bracket and just cut some length off of the old water outlet hose.

Now I started the smaller component installation. Starter, sender wires, oil filter w/bracket. As I am going through this process I am slowly trying to clean up any rust that I can.

Here is where the third speed bump came in. I took the time to straight file the face of the shaft coupler and clean up any corrosion/rust. I even cleaned and lapped the shaft for proper fit. I installed the shaft coupler and the PPS Shaft seal onto the shaft as I was putting the shaft back in. I then tried to begin the alignment process. Well it did not mate up and after some discussions on one of the forums I decided that it must be to out of alignment to mate (this was a hard decision and one I would regret). So I started moving the motor around to get it in alignment to get the no resistance mate. However, if you look at the picture below the faces were almost perfectly in align already, so the movement was a shot in the dark.

Well, after a lot of movement and no luck in mating. I removed the coupler and pushed the shaft aft. Well… Still no mate. So I inspected the v-drive coupler and found that there was some pitting in the female side of the mate that was not allowing the couplers to mate. After doing some minor improvements on the female side to remove the pitting I was able to get a perfect resistance free mate. So I installed the coupler back on the shaft and started the alignment process again. Note: I will always assure a perfect mate with the couplers alone before installing the shaft. I made sure the shaft was center of the outlet on the bottom of the boat (BTW It wasn’t even close thanks to my above speed bump). Once centered of the outlet (using old piece of hose to help with this). I went back up top to align the motor as best I could to the center of the shaft without mating. Once it was pretty center visibly I mated the coupler with no resistance and started the feeler gauge process. Using the method outlined in the Owner’s manual I did the alignment and bolted everything back up. Installed all of the hoses and wires back to their original place. Moved the fuel tank and ballasts back to their spots. Took it for a test drive. Only issue was a slight leak around the shaft seal that was due to the allen screws not aligning to the indentions.

Hope this will help someone in the future that might take on this task. Searching I was limited on information that was out there on this installation, so I thought I would add some to assist.
