    454 in a 21' bowrider

    I have the carbed 454 Mag w/ B3 in my 220 cuddy. To be perfectly honest, I believe the boat is way over powered, for what it is. The big plus is ability to pull a large load behind (like more than 1 skier or a big tube) and get up on plane very quickly. It's fun, but can only "have fun" with...

    Making a pressure tester for Mercruiser outdrive

    30 psi gauge is only $9.00 at Ace hardware. I just bought one to test someone else's cooling system to verify a freeze crack.

    Oil pressure

    That's not a leak. It is a gaping hole if coming out as fast as it goes in.

    350 mag mpi fuel cooler removal help

    Actually, buying the Hardin S/S plugs is cheaper (when bought in a pack of 5 for $25) than the OEM plastic ones. Have used the Hardins in my last 3 boats and have never had a problem with them. Amazon has the blue plastics for $10 for 10 (but bet they are cheapie Chicom knock offs)...

    Caddy XT5 Towing Capability

    My CT6 has the 6 cyl 3.0 twin turbo (404 hp) and when it shifts from 6 to 4 or back it isn't even noticeable, except for the indicator on the dash. Have heard there is a setting or driving mode to disable (forgot what it was), but haven't bothered since it displays no bad manners and gets...

    Fuel Gauge making full, even with no power.

    Probably. The gauge sender minimum resistance is 33 ohms (240-33), 33 ohms being FULL and 240 empty. Grounding it, dropped the 33 to zero. You effectively shorted it out and smoked the gauge.

    Pinion gear timing to driven gears in B3 upper housing

    Do you need the actual Mercruiser Bravo drive rebuild manual? I have Manual 28 in PDF if you need it. Has a full rebuild section in it and bet it is 100 time more complete than the Seloc manual.

    Where can this water be coming from?

    Maybe get a cheap borescope (a bluetooth / WiFi one can be had on Amazon for cheap) and have a peek back there while running. Won't show a leaking core plug behind the flywheel, but will show a core plug on back of head or a weeping head gasket. Maybe you can get your phone camera back there to...

    Water leak into bilge

    Bad bellows Bad "Y" pipe Bad transom assy / seal I would look real hard at this one. Bad steering pin seal (My B3 did this and would leak about a gallon an hour into bilge just sitting). Does your drive have a lot of play in it? Have some slop up and down? Replaced steering pin and everything...
