    Rocker oil flow on a 3.0? Is any flow good?

    My motor was rebuilt by someone else - had the cam gear slip and bang up one of the lifters. Now I repaired it, replaced all lifters and spun the motor around a few times to get oil flowing through the new lifters - adjust the rockers and test run. I don't know if there is a simple answer to...

    Repairing my new 77 Johnson 115 - water tubes from the impeller housing destroyed....

    I've not seen this problem till now - It looks like someone had replaced the impeller and when putting the lower end on, instead of pushing it into place by hand, they used the mounting bolts and smashed the tubes up bad.... are these replaceable? They're copper so I guess I could just sweat in...

    Xmas upgrade - what do you think trim tabs or a ss prop

    Hey guys, everyone says that ss props are more efficient and trim tabs make your boat more efficient, if you had to choose one what would you say? I have a really good deal on the trim tabs so to me its a very close cost. I have a fresh 3.0 Volvo penta with Cobra SX od that has a hydrofoil...

    rebuilt motor breakin?

    Okay motor is almost completely rebuilt - went .20 over cylinder bore, .10 crank and flat top pistons. New cam, intake/exhaust manifold, riser, exhaust, flywheel, oil pump, oil pickup and rods. I had the head and block cleaned and machined true. I would say this motor is as close to new as I can...

    flat top pistons okay? 3.0 181 rebuild

    Hey guys, the OEM pistons are dished and the master kit I just recieved came with flat pistons. I have always just replaced engine parts with the same parts, never really got into raising compression for HP or whatever.... Other than some timing/fuel adjustments -what are your thoughts on flat...

    gps - chartplotter mounting location

    Hey guys, wondering if anyone knows what this feature is for or if anyone has mounted a gps/chartplotter here (there is a raised flat platform in front of the drivers window)? It seems like this spot would be more in the elements but it looks to be the best spot - what do you think?

    This cannot be right - gap behind motor to transom mount??

    Re: This cannot be right - gap behind motor to transom mount?? After a couple of days searching online, I spent a full day trying to find a machine shop. I am having 3/16" shaved off for $70 which is a lot cheaper than getting another flywheel or housing, but for future reference any ideas will...

    Penta 3.0 interchangable top end parts?

    I need a head and intake/exhaust for a Volvo Penta 3.0 which are pricey but I see OMC and mercrusier parts all over for a lot less. From pics it looks all the same - GM block w/ a GM head (but with different names stamped in) and for the most part I found the intake/exhaust mani's all look the...

It's been quite a task getting the motor to where its at now (white silicone...
