    OMC/ Volvo penta 3.0gs ignition fuse keeps blowing

    The fuse is sized to protect the wire, if the fuse blows the circuit is drawing too much amperage, therefore the fuse blows. You need to find out why. Check all connections in the ignition circuit for high resistance/oxidation/corrosion. You will need a wiring diagram for your model, start with...

    Relocating oil filter on a Mercruiser 5.7?

    I didn’t even try to change it with the engine in place because I didn’t want to bugger up the removal of the old one. There’s just no easy way to get at it; Id have to use an inspection mirror just to see it. So as long as I still have to pull the seats to winterize its not a big deal to get...

    Is a closed cooling system safe for cooling the engine at higher r.p.m. runs? Pro's& Con's.please.

    While raw water cooling has an unlimited supply of cool water, a closed system is pressurized, which prevents localized boiling in hotter parts of the system (cyl heads, valve seats) so if the system is designed with enough cooling capacity, it should provide improved cooling. It also allows the...

    Relocating oil filter on a Mercruiser 5.7?

    Some will recall I bought a remote filter kit from Michigan Motorz, same as they sell on their turn key motors, with a Canton Racing mount for the adapter, and I asked them about the 30 psi bypass. They said they don't do it, and have sold many engines with the standard bypass, but I felt that I...

    1997 Mercruiser 5.7 Electric Fuel Pump Conversion

    You could install a solenoid with the correct # of terminals. What you have is the 3 terminal style but what you need is the 4 terminal style.

    Can I Tell if Water is Getting into the U-Joint Bellows?

    Unfortunately the only way to do that is to pull the drive. Now as a practical matter I have only had water in the bellows once, that was way back in 2005 before I took over the maintenance on the sterndrive. The shop I was using installed a new bellows & gimble bearing. After that I built a...

    Rebuild old mechanical Fuel pump or go for Electric Fuel pump

    If re powering I’d actually take a pre Vortec because I can still use a mechanical pump and the heated air intake for the Quadrajet auto choke….I think both are more reliable than the electric equivalents…..

    Grease Zerk Fitting Question . . .

    I’ve got an original old one of those, it was given to me by a family friend who used to run his own limo business here in LI, he’s 94 years old so who knows how old this thing is!

    Mercruiser 496 MAG Refresh Thread

    I would say that anything that might possibly fail and result in the need to pull the engine again, I'd for sure do it now. That includes all possible leak areas on the transom mount/exhaust Y pipe, etc.

    Grease Zerk Fitting Question . . .

    Maybe it’s because very few vehicles actually have had grease fittings in the last 30/40 years! My last vehicle that had them is our 1998 Grand Cherokee! Before that it was our early to mid 70s GM full-size cars…

    OMC COBRA 5.8 EFI and ESA

    http://www.hastings.org/~stuart/cobra/ don't know if you have seen this site, but there is some original OMC documentation on this site, that will help explain the finer points of adjusting these, like: setting the shift rod height (very important) how much the travel of the shift cable should...

    Boat leaking salt water - steering pin?

    For there to be that much alu corrosion in that time frame, there's likely to be a loose hose clamp on one of the raw water intake hoses or the fitting for them on the inner transom mount. Just a spray of salt water mist + sitting in salty air, can do that.

    Boat leaking salt water - steering pin?

    On my boat I'm obssessive about making sure there are no coolant leaks and also everything, engine & inner transom, steering system, etc gets sprayed with Corrosion X every year. Still running the original 36 year old oil pan and timing cover, both are known to rust out if not treated often. It...

    Simple winterization process / draining 4.3gl

    My pleasure! I grew up with American cars back in the 70’s so these old school GM marine engines are just like what our Chevrolets had back then even down to the Quadrajet 4bbl. That was the easy part…. The marine stuff is what I had to learn…

    Simple winterization process / draining 4.3gl

    Sounds like you’ve got it done! Now for next year you’ll be all set! I taught myself this stuff about 20 years ago, started out with the winterizing & fluid changes and over time started doing more & more like the outdrive maintenance, fiberglass work, repairing wiring issues, etc. The biggest...
