Hi guys, I have acquired a complete boat with a 4.3L merc (2bbl 12 bolt intake) with an Alpha one that I plan on swapping into my 1989 Bayliner capri 1750. I like my boat and enjoy wrenching on it. I have already done the stringers and transom and interior so the boat it solid. I have always wanted to put a 4.3 in it so here goes.
The motor serial is 0C525578 and the drive is 0C684021. I believe the engine and drive are late 80's but not sure. I got the engine running. compression is 125 psi. Battery was low so I think the numbers could come up with a fresh charge. The drive fluid is clean with no water in it. I will pressure check it later.
My question are this. How much play is allowed if any in the shift shaft rod, the part that connects to the bellcrank on the bellhousing? Mine has some side to side movement. Is this supposed to be tight?
The ujoints are rusty, and the gimbal bearing is seized. Should I replace the drive shaft seal along with the ujoints? The seal does not appear to be leaking but the job to do the ujoints is big and seams to be silly not too.
Should I be concerned with preload if do the seal? Can I just reassemble? I do have the service manual from the sticky, but Im a bit nervous about diving into that. Any input on this would be great.
Thanks Stu
