I've happily given out FAR more FREE work than I'll ever get in PAID work. I view it as a blessing that keeps on giving. If I treat people well, and help them when I can, maybe I don't get the cherry jobs, and maybe I do. The cutthroat guy down the street charges for every second of his time, and all his stuff is paid for. He's known as "Rapin' Ray" but people keep going back over and over and paying his rates. I'm starving to death, but I will never operate like he does. Goes against the way I was raised.
If I'm going to "drop by" and help somebody, I don't consider it billable time. If I plan to offer paid services for additional work, I make it clear that I'm interested in carrying the job farther for pay.
But like I say, I'm starving so maybe I'm not the right guy to listen to about what's the right way and what's the wrong way..

Ditto MC can't count how many drives,transmissions,water pumps,fuel pumps,impellors, we've changed/swapped out for fellow boaters on the weekend for Pizza & pitchers of beer when the town marina service shop was closed just so they could still enjoy there boat .

you say the engines only have 5 hr's on them? talk to the builder and see if theirs any warranty!! also cut open the oil filter on the other motor and compare the metal particles,could be from brake in..if the cam is going south it usually starts at the top of the lobe and not the side..
as for your next cam talk to bob madara @ marine kinetics,he is to cam god on here..

I think I would only put solid lifters in something that was a little easer to work on. Harley motor comes to mind. Then again if you were raceing your boat guess you take advantage of what you can.

Well not the best night, re adjusted lash on all valves tonight which went really smooth. Took them to .010 like the engien builder said. Well after learning how to properly do it, realized they where all within .002 of .010 already. Even the one that was measuring .040 before. Well what I realized is that as the cam turns this one rocker/cam lobe would loosen up to about .040 as the cam turns. So basically my heart sank right there and then, cause I knew it was the cam. I adjusted it anyways so that when it came to the loosest part on the lobe is was measuring .012, re assembled everything and fired for just a second or two. Yep still knocks. Shut it down, pulled oil filter and cut it open with tin snips. It has a fair amount of very very small metal particles, sitting on the bottom of the fiilter housing. So I have come to the conclusion I have a **** cam lobe, does that sound correct? Next question is the rest of the motor trashed cause it ran for a little while with the metal in the oil? It still runs sweet, but I am not sure how to proceed forward at this point. My feelings are this, pull both motors, new more agressive cams, new hydraulic roller lifters, and new push rods for both. It is so freaking windy out there. Had this boat 6 days, feeling pretty sweet right now!!!
if you are going to change the cams, i suggest you get in contact with Bob, "RMbuilder" of Marine Kinetics. he is very reputable and very good to work with! he will not steer you in the wrong direction! he'll be able to help you out with your whole valve train. i am very impressed with him personally!

sorry to hear that! I would pull your v/c and check and see if that one rocker in question is loose again. from there, pull the rocker and inspect the pushrod to make sure it's not bent. if it's straight, pull the intake to get to the lifter so you can inspect that. if the lifter looks good, inspect the lobe on the cam. you should find the culprit somewhere in there. to answer your question about "is the motor trashed?".....ive been down this road twice! it sucks! DO NOT just flush the motor and replace the lifter if it's a bad lifter! eventually you will end up with a rod knock! the shavings that you have already found in the filter indicate that something is very wrong. if you where to keep running it, those shavings will embed themselves into your bearings and wipe out your crank journals, and also embed themselves in the sides of your pistons and wipe out the shirts.

ALSO...MOREL LIFTERS ARE TOP NOTCH! IF YOUR GOING HYD. ROLLER, I WOULDN'T PUT ANYTHING ELSE IN MY MOTOR. FOR SOLID ROLLER I FIRMLY BELIEVE IN THE BEST CROWERS YOU CAN BUY. (cheap solid roller lifters is what caused me to have to rebuild my motor twice. the second time it happen, I flushed the motor and stuck another lifter in it....it didn't last a long time and the shavings destroyed my crank and pistons).
