Yes your bringing up some good points. I guess patience will be the key here. Alaska summers are short. It sucks not having my boat!!

Well first things first I suppose have to figure out how to lift the engine out now!!

There's always a chance that the shop may find your block has some issue that can't be fixed. At that point, it may be worth considering a short/long block instead for time/money sake. Or you may end up paying to bore the block/turn the crank/etc unnecessarily. once a 302 is .030 over, that's about as far as you can go. Next time, you would likely need a new block. I've heard .040 is doable for a car, but it makes the jacket too thin for the rigors of marine use. You may only need a hone, or it may have already been bored in the past. You just won't know till the shop gets it.

Just some thoughts.

This boat is cursed I'm sure of it. I have never had it go longer then 5 hours without something major breaking...Here is the run down..

Bought boat...

Dual helm custom steering cable breaks..replaced
Starter locks out on the flywheel and burns up...replaced
Alternator goes bad..replaced
Carb float gets stuck...rebuilt
Stern drive blows gears into pieces..replaced with newer alpha 1
Water pump..replaced
Starter solenoid dies...replaced
Batteries died..replaced
Plugs, wires, cap, rotor, upgrade to electronic ignition..replaced

All of these things happened one at a time all out on the water.

This weekend after replacing the stern drive with a rebuilt one I am 10 miles out of Homer, AK and the engine coupler shears the spline teeth.

Now I am faced with pulling the motor I guess unless anyone knows any tricks. I don't understand why it would rip the teeth right off the coupler but it did. When I pulled the drive shaft out the teeth on that were fine but were filled with what was left of the couplers spline teeth.

A week ago I did a compression check...All cyls have 110psi or higher except #6 which wouldn't blow better than a 70psi. This must be my engine vibration problem which I have not solved.

Question to the board would be..what would you do. The boat hull and interior all in excellent shape.

Should I pull the engine and rebuild??

Convert it to a outdrive setup??

Ditch the old 888 setup and find a volvo setup??

I have over $3000 in parts on this thing now.

Who sells good rebuild kits for the old ford 302 blocks?

Does this engine spin backwards?

Should I set it on fire?:confused:

Just a different point of view or perspective... If you are considering a repower why not dump the ford and go with the GM. 305 or 350 marine blocks they are much cheaper than the ford counterparts and places like Jasper sell complete long block with warranty 1-2 years depending. A low compression reading will not give you a "vibration" issue. A misalignment issue will do 2 thing: Will give you a "transferred" vibration (coming from the drive shaft and U joints) and 2: It will eventually wipe out the engine coupler. Normally a misalignment is caused by a motor mount gone a rye due to rot somewhere where the mounting lag bolts are located. You will find which when you pull the motor.

Howdy,


and welcome to iBoats!


When you post a reply to a thread, it might be a good idea to have a look at the actual date of the thread.


You just replied to a thread that had a last post date of JUNE 2007.


that guy may not even be alive now.......at the least, he's probably already sold or junked that old boat!!

His last post was in MAY of 2010........

don't fret though.........we've all done it!!!!!:D



Cheers,


Rick
