Looks all too familiar. My 73 skier was just one rotten piece of rot after another. Just when you thought you might get away with not replacing this or that you are quickly reminded that EVERYTHING is rotten. I could squeeze water out of my transom lift ring assembly and it is 2" up in the air. That was the final piece that made me realize nothing was safe.

You are doing the right thing and will have a sweet new/old boat when you are done.

Well got more done on the sep! revamped the mobile bunk so it was usable to do all repairs, and not having to put on stationary bunk. do to not wanting grinding dust in my shop the brackets slid in and out and are ajustable up and down. removed almost all rotten wood, just keel board left, you know who you are that talked me into this, bfn. picked up all my wet sanding stuff today for deck and hull, starting at 600 then 1000 to 2000 then 4000. the last pic is of a test sand with 2000 just to check it out. hope you can see it in the pic Jeff

Wow, thats amazing. I guess if you didn't know any better one would think leaving a hole like that was ok. Man were they wrong!!!!

Seems like it may be overkill but if you have time and energy, it's not going to hurt anything.

Thats one interesting speedo.

Hey guys, is the exhaust thru hull original to this boat? If so, I wonder why it was placed so high on the transom? It seems that being so high would be annoying from a sound perspective. Jeff, with your new power, will you be staying with the single exhaust outlet? Will you be keeping it that high on the transom? Just curious. Nice project and nice work

Steve,
The I/O's I've seen had the normal through the prop exhaust like Jeff's. However, when the Seperator/Torino/Spoiler hulls were set up with V drives, two different exhausts though the transoms were used. The early hulls were set up exiting high since the exhaust manifolds exits were towards the aft and went directly out from there. Then later (maybe to quite them down) the manifolds were reversed so the exits pointed forward. Then, they made a "U" bend down into the bilge and aft exiting the transom at a level common to the DD's. Real late in the V/D's life, I even think CC installed mufflers down under the engine.

That "flapper" on Jeffs transom is for the bilge ventilator.

Worked on the sep today, removed the keel board [thanks tim] it wasnt rotten but it was soaked all wiring removed and also got the old mercruiser throttle out. we also removed the window all the bolts had to be cut do to severe rust, what a pain so little room. just about have the hull stripped for wet sanding. waiting for a decent day to get the hull outside to finish grinding inside so we can get to glassing. here is some pics from today. btw what did cc use to seal window to hull. boat kinda looks like a donzi wiyhout window

if your going to skin the wood off the transom, buy yourself a portable hand planer, works well, I have a ton of Chevy Merc takeouts with all the ornaments hanging if you need any parts. google silent choice, alot of Mercs use them,

you gotta watch, if you purchase a pre 86 chubby, it is a 2 piece rear main with different crank which warrants a different alpha drive coupling, after 86 is a 1 piece rear main, and to a different coupling....a little pricey and worth purchasing a new one because they tend to fail often.

also, if you put a new gimble bearing in and U-joints, which i hope you would while its off, buy them from Napa and not Merc....Merc gimble bearings and u-joints deleted the zerc fittings and a grease hole on the bearing so you cant service them....bastards

if you do happen to go with thru hull, they do make a set of baffles, believe me the noise will be annoying as fck after a while, the baffles tame down the noise a bit and the complaints, open exhaust on an I/o is a touch louder than the norm of an inboard

Good morning eric! yes the chubby is a 1 piece rear main, the newer OD is a 87model do ya think there will be a problem. was thinking of going with either aluminum mercruiser replacements 650 complete or the MP2K from michigan motors 1300 bones. the manifold are a long way off but need to be considered during this build do to steering clearance. so the planer will take the thin layer of wood off transom, good idea that was my next project considering baffles but dont know if i have enough room. here is a pick of todays project, removed bow lift ring supports that was the last piece of rotten wood thats coming out and was one of the toughest. if any body thinks thay can leave any wood in during a resto look at this!

the baffles are about the size of a coffee can cut in half and mount directly to the transom and they have their own outlet tips that go out the back of the boat, cuts the open header noise in half, really is annoying with straight pipes on I/O's. when it comes to manifolds on these boats i can always think of better ways to spend the money, if its open checkbook, go with your gut. But, I think a pair of Mercs would be the way to go. if your going with a stroked engine there is plenty of useable horsepower
1986 is when they switched to a one piece RM, so the 87 coupling will fit on the crank. when you get to the point of aligning the engine to the drive i will send you my extra tool, but i need it back.
The planer is definitely the way to go to skin the transom, it gets right down to the glass, I have a twin engine boat i have to put a transom in next month and i am not looking forward to it, I threw him a high price to dis courage him and he said OK, when should i bring it? fckkkkkk!!! not so bad though I guess, I need something to fill my days

now you know what i do in between transmissions lol, put my share of transoms in and alot of repairs on the Alpha/ gimble rings, crack the drive in half and put a new impeller in there, new rubber and shift cable...dont ask why just do it... lol really, invest in a new shift cable to the drive or the boat will stall everytime you put it into reverse because of the interupter switch.

Hey Connorsons
I have to give a plug for an oscillating tool for that transom.   I cannot tell you how much I love my Rein multimaster. I have recited so many boats with it I cannot even count. Of course the market is flooded with them now. I heard their patent expired ...I have seen dremel Milwaukee Bosch Rockwell and even Harbor Freight with oscillating tool models. Don't skimp on the blades though. I tried a HF. Blade for kicks and it lasted about 30 min before the teeth were rounded. By comparison some of my Rein blades are years old. I have bought Bosch blades in a pinch and they seem to hold up pretty well.
