WOT and acceleration issues!

Donno,... Sounds like You're workin' on an In-line,+ your Manual is workin' on a V-motor...

I also checked the manual for the 3.0 engine and what he said is right... It says take the inlet manifold off... and nothing about the side plate. I was a little surprised too....

Well thank you for clearing it up for me!

Re: WOT and acceleration issues!

So, I really didn't want to do it because I knew what the answer was going to be and really wanted to take the boat out this weekend, but I pulled a couple main caps off to check what the bearing looked like since there was obviously a lot of metal shavings from the old cam. Well... just check out the pictures. I'm pretty sure those are suppose to be smooth... So I guess this means a complete tear down, cleaning, polishing of the crank, and reassembly.

Will one of the Mercruiser V-8 motors fit in a 95 Bayliner Capri 1850? Or how much more power does the 6-cylinder make over my 135hp 4-cylinder?

A 4.3 V-6 should make around 200 horsepower.

Re: WOT and acceleration issues!

Ok, got all new components, crank has been turned, everything is clean. I'm going to install new rings on my pistons and I ran into a snag. I have Enginetech rings and need to know which ones go where and in what orientation. The manual says "marked side up", well these aren't marked. There are 4 unmarked square ones (meaning no chamfer or any distinguished difference from 'up' or 'down'), those are the top grooves or bottoms? And since they are unmarked, I was told these can go either way. Then the other 4 have a chamfer in them. I was told the chamfer points up. Correct? The confusion was that they also have a dot on them on the other side that doesn't have the chamfer in them. Part number is R40056-STD. Thanks!

Best of luck on that rebuild. I bit of advice before you get too carried away, you're asking questions which are considered basic knowledge to a mechanic for an engine rebuild. Get a mechanic friend to oversee your work or you could risk spending more money all over again. I'm a licensed auto mechanic and it took 4 years of training just to get the ticket. You wern't let near an engine rebuild till you had 2 years training under your belt. I've seen way too many botched engine jobs due to a small unnoticed error in assembly.

Well that's not really an option. I am going by the book on everything and I do have a guide from a local engine builder, but he isn't over my shoulder. The easy answer was the marked side up. But there isn't a "marked side". So could you just answer the question?

Re: WOT and acceleration issues!

As I recall there should be 3 rings for each piston. The chamfer'd ring with the chamfer toward the top of the piston is the top ring, then the second ring (no up or down for it) and in the third groove will be your oil ring

Thanks, that's what I thought, just wanted to double check. The "oil ring" is actually 2 rings with a 'wavey' ring as the spacer.
