no need. a 11" clutch flywheel is 168 tooth, a 10" clutch flywheel is 153 tooth. sometimes incorrectly called a 14" flywheel and 13" flywheel
been that way since the birth of the SBC/BBC all SBC/BBC ring gear pitch has been the same since the beginning as well. copied over from the early...
if the flywheel housing is set up for the 168 tooth flywheel, then yes. the motors are internally balanced which is why the crank changed from the non-balance shaft motors to the balance shaft motors.
Your 1984 is an AQ series drive. If it's a 290, it's aa much better drive than a bravo, and 10000 times better than an alpha
Only way to bolt in a Mercruiser in that boat is if you redo your transom
You already bought it. You have buyers remorse.
Worrying about what something cost 15 years ago after you may or may not have over paid is like worrying about a grenade after you pulled the pin and tossed it.
I bought a used boat 15 years ago, sold it 3 years later for 85% of what I paid...
only one boat out of about a million only had a soft deck and not need transom, stringers, and new foam.
all the information you need is in the stickies at the top of the forum. 4th sticky down, links 14, 15, 18, 2, 3, 4a, and 4b.
no need for epoxy
based on the pic......that transom is rotten. only way to stick a screw driver into a good transom is with a 5# fist maul. take a 5/16" drill bit, drill into it about 1" deep from the inside at a few places. bet the shavings come out dark, wet and smelling like rotten mulch
easy way to check the transom. get two heavy buddies nicknamed tiny, trim the motor up fully, both jump up and down on the lower unit.
there should be zero transom flex.
dont worry about hurting anything, a good transom will take 1500# or more of load
additionally, if there is an aluminum...
1 - NO
2 - depends on the type of corrosion
quality tinned marine wire would not corrode like that, however cheap wire does. unfortunately most boat builders use cheap wire because as long as the boat lasts longer than the 5 year warranty period, that is all that matters. boats are designed...
any rot in the transom means the transom must be replaced.
because years before there is rot, there is moisture and the mildew and fungus that eats the wood is already there
