The SJ twin jumped right up on plain and the handling was good for a big boat. I never really got on to the correct use of the trim tabs and the turning radius was pretty wide at speed. My guess at top speed would be about 50 MPH. The controls were located next the the drivers right thigh with 2 throttles and 2 gear shifts in an area of about 4" X 4". This placement and design was p... poor and made tight maneuvering difficult to say the least. That aside, the twin SJ was a great boat that sounded awesome with those 4 copper exhaust pipes burbling like an old Chris.

Geeze. You guys under 40. We got back in the boat the same way as we did in Chris Crafts, Hackers, Trojans, Centuries and all the other inboards - everyone carried a folding ladder that hooked over the side of the boat. Very few used double boots back then. If you did, the rear was just small heal cup. You put your ski on after you jumped in the water, and you used a folding ladder to get back in. If you forgot the ladder, you stuck a foot on a spray rail and someone grabbed your arm and pulled you in. No big deal BKH |

Well, Sam, all I can say is you better not go for a captains license. A twin is fantastic for tight maneuvering. What do you want, a bow truster??? |

I think he means the positioning of the controls were poor Pete

Pete,
Normally, the controls for a twin are in front of you with the port side on the left and the starboard on the right and you operate them with the right and left hands respectively. But when the controls for both engines are mounted low on one side out of your line of vision, it's a different story. Incidentally, I had a 6-pack license but had to give it up when my heart went bad. I could get the license back now that I have a new heart, but I don't feel like chartering at my age. Sam |

Many years ago a guy in our club [Chris Labonte...now deceased]] had a SJ with the twin 302's. I lined up my Nautique of the moment [can't remember if it was the '76 or the '81] to see how closely they ran and was amazed at how closely they did run!! Out of the hole the Nautique was quicker but not by as much as one might think and from a rolling start that beast ran right up with the Nautique!! Probably not 50mph as has been previously mentioned here but not very far off. All in all very impressive big old boat!! |

My twin 302 SJ came from Sandusky which is not too far from Avon Lake. It was the Sportsman model (no cuddy) in white with red upholstery. It may have been the same boat.

The drain plug is likely at the end of the hose attached to the porta-potty.

Hey guys... questions. I'm trying to figure out how to winterize. I've never seen this kind of cooling. There is one through hull intake that goes to the rear, into a U, and then back forward under the port side of the engine. I can't tell what it is doing after that.
This coolant reservoir on the stbd side... what is it? How does this system work? Going to crawl around a bit more to see what's what right now. |

Sea Maxx is closed cooling version of a PCM engine. Here is a manual
with a parts break down and diagram. http://engines1.novosolutions.net/print.asp?id=6&Lang=1&SID= Cooling to the internal components uses coolant through a heat exchanger as your car uses a radiator. Freshwater is used to cool the heat exchanger (radiator) as there is no fan or air pushing over fins as you have in your car. I think that freshwater is also used to cool the exhaust manifolds. BKH |

Thanks Brian. That helps. It does look like the freshwater cools the exhaust manifolds. I still can't find the through-hull drain.

Sorry, I should have been using the term seawater or raw water, not freshwater. BKH

OK I was at it again today. I finally have 99% of the mussels and junk off the hull. I used an ice scraper today and it worked well. After my third trip to the power washer in the last 10 days, it no longer smells like the Atlantic Ocean.
The bottom paint was actually coming off fairly easy with the power washer. There are so many layers... the current black, which has several coats, and below that is a white and a blue layer. In some very small spots, all that came down right to the gelcoat. I also came up with a few plans for lifting the engine. That is planned for Friday or Saturday. So the weekend ended better than it started and the weather finally cooperated today. Also, the 3-car garage that I was planning on renting looks like it might work out. Unfortunately it's too low to lift the engine in there, but I can get it lifted at home or my parents house and bring it there. A few other things I noticed:

I got the engine out today. It was not fun. Ended up hanging chains between two trees and using a chain fall to lift it. That worked out fine, but it just took a lot of time.
I wonder if this engine is even fixable. -The exhaust manifolds are completely rusted out. -The oil pan needs to be replaced. -The heads look very rusty and maybe need to be replaced. - The plate between the bell housing and the block is so rusted out that it had a huge open gap. (what is this called?) -Fuel line was about ready to burst. -So much rust and corrosion on the transmission -One of the transmission mounts is broken and probably not fixable Pics: |

Curious to see the pics. If you need heads, manifolds, etc. but the block, crank, cam are ok plus the EFI system is workable, seems like it might be worth a rebuild. 350 parts are certainly easy enough to source.

Have you pressure checked them or are you simply looking at outside surface rust? |

Pressure test or not Pete,saltwater manifolds don't last
long and to go with a rebuilt engine,he should just get new ones.Once the salt gets in the castings you can never get it out, it keeps leaching.He might be best to cut them off. Jeff it seems you Easterners prefer the two tree method of engine removal as opposed to the Midwest's one tree. Yours will be archived |

Forgot to mention that it does look better cleaned up. You might also be on the lookout for new or used freshwater motor mounts,those will be tough to repair,the actual threads will most likely be rusted away

Can I simplify this engine and make it fresh water cooling now?
Gary - I wish I could have found one tree that worked well. One branch would have been much easier than running the span with chains across the trees. I should have just put an ad in Craigslist looking for someone with a bucket loader or lift. I probably could have gotten it done in 1/3 the time. I could tell the threads were bad on the rear mounts. The fronts look salvageable. |

I think the threads on the rear are fine thread,thats why they rusted easily. With the tree method your not waiting on someone else and then feeling you have to hurry. |

When I built my house 20 years ago I had 2 of the garage roof trusses engineered to each support 1500 lbs. in addition to the regular snow load. I then installed an eyebolt through the ceiling to attach to each of the 2 special trusses located over the front lift ring and rear lift ring of a boat onto which I can hang a chain hoist. To pull an engine, I position the engine under the front chain hoist, lift the engine, and roll the boat out from under the suspended engine. This has worked out for me many times over the years with never a problem.

You mean raw water cooled, right? "Fresh water" cooled is actually antifreeze cooled. And "Raw water" cooled is actually fresh water cooled. Kind of confusing. But yes, I would think that if you'll be running it in fresh water you could run raw water cooling. |

It's been a while but over the last few weeks I've remove the SJ off my brother-in-law's trailer and have it blocked up on a concrete pad.
I just got a chance to explore a bit yesterday and wow is it mushy. Check out this video. Don't forget to select HD. |
