Will do!

Hello all,

Time for an update.
With the summer coming up last year it was difficult to find the time and motivation to continue working on the boat. After the two blower screws went through the hull, we went and enjoyed the good weather, and spent some time on the water with our I/O.
Also had the chance to see a certain red boat in action, which some of you might recognize Big smile


Due to work trips and vacation, we didn't really manage to start back up. Now, a few months before summer begins we realized once again that we need to finish this boat ASAP. So over the last week we painted the engine block and put it back together, installed the steering, horn and throttle control, also finished up the floor boards. We're waiting on some parts for the engine (fuel pump and some gaskets), for the fuel tank, etc etc.
I'll update soon with pictures and , probably, a ton of questions.



Cheers,
Lenny

If someone can find the owner of that red boat they need to tell them to add more power to it, looks like it only is pulling a dozen people ... LOL

Nice looking work space!

Quick question:
Would you install the engine & trans before or after installing the carpet?

Also, if anyone from the EU has some info on shops where we can find carpet, i'm all ears.
We can find some, but its either very expensive or very little choice.

I installed the carpet before the engine was back in.  Made fitting the carpet to the boat shape much, much easier. 

Link below is to the section of my rebuild where the carpet started going in.  I managed to install it as one piece, turned the floor carpet right up the sides with no cutting.  Only had one spot on each side that ended up with a fold and that was up just at the dash so not visible.  A fiberglass mat roller or some type of roughly 6" wide hand roller is a must for getting the bubbles out of the carpet.

Type and amount of carpet and glue I used is noted in one of the posts.  Not sure if that going help you in the EU.

Update:

We found carpet with a correct price and neutral color. Originally we wanted to go with teak like carpet, but quite happy on how the grey turned out.
Last picture also gives a good look on the footrest, it's a bit narrow, but it will do fine I believe. (we could always add a piece to it, if necessary.

Attached the gearbox to the engine, and dropped it into the cradle.



So now come the questions Smile

-Attaching the belhousing to the engine.
I sorted the screws in a separate bag for the belhousing, but these don't seem to match... I have 2 bolts (the longest ones) that fit nicely in the bottom hole, on each side of the housing. (marked in RED below) I'm guessing these are the 2"3/4 ones. above those holes you have the "guide holes" and on top of these you have the Holes for the studs I believe? (GREEN) For the top 2 holes (YELLOW), the blowapart states that I need  2x 1"1/4 bolt. Which are not in the bag. The reason I'm confused is because the bolts I do have in the bag are too long but one has a painted head and the other one doesn't, this would make sense because one of the bolts is installed inside of the bellhousing (under the starter), so it wouldn't be painted over during the painting process)
So either I'm loosing my mind or the machine shop took the bolts out of the bags and switched them up by accident...

-Engine support blocks
I have 4 Engine support blocks, is it possible that there are 2 that go under the engine mount pad and 2 that are placed on the inner side of the transmission mount? Or maybe one on top of the cradle and one beneath it?

Looking at pictures of my 86 silver nautique engine, I only had two engine support blocks and they went under the front two engine mounts, on top of the aluminum cradle.  Picture is BEFORE the rebuild, everything is much prettier now.

Thanks Andrew, your boat certainly is looking a lot better now!
I did some digging in the photos that were made when this boat was disassembled. (2005)
Found this:
First picture showing the engine mounting plates on top of each other. Can anyone confirm this is how its supodsed to be on a 1986 BFN?

Second image showing the transmission mounts, only attached on the top and no bolts on the side. there's quite the gap between the cradle and the mount. Not sure that's the way it's supposed to be...

Not uncommon to see some blocks under the front mounts. Boat was designed with both Chevy and ford engines in mind. Notch in stringer below the mount is to get the nuts on the backside of the through bolts. It’s common for there to be a small gap on the vertical face, it’s not critical. Obviously the tabbed cradle boats (89+ SN) don’t require any vertical support. Can’t recall if that angle on the underside of the mount is sharp or radiused, might not be possible to get the mount all the way in on a piece of sharp angled aluminum like they could on the radiused stringers (cradle-less) boats.

Engine mount has a sharp inside corner.  That's the back mount but the front mount has the same sharp inside corner.

Could be deceiving but looks radiused in that pic.

I expanded the original picture on my computer..., just a touch of radius, an 1/8 or less at a guess.  Didn't interfere with my engine placement, would need less than an 1/8" on either side of the cradle to clear it.
