    Stalled in rough water, kinda scary...

    1991 Sea Ray 225 BR 7.4 carburetor, mechanical fuel pump Returning to Dana Point from Avalon (CA), pretty rough conditions, 3-4 foot seas with lots of wind waves. Boat was getting tossed around a lot, sometimes a bit violently. I didn't have a lot of gas in the tank, but enough to get back...

    FUEL PRESSURE - where to test, how many PSI?

    I'm troubleshooting (again!) the fuel system on my 1991 454 mercruiser (carbureted). Two questions: 1) Can I put the gauge before the fuel pump (convenient), or does it have to go between the fuel pump and the carburetor? 2) How many PSI should it be? Thanks!!

    Who needs a thermostat?

    As I have benefited much from the wisdom found on this forum, here is something I am 'giving back'... About six years ago my boat was being worked on by Tom at Lake Powell Water World in Page, Arizona. He is a former race boat kind of guy, great mechanic... He looks at my boat and the first...

    Stranded in the Catalina channel!

    I have a 1991 Sea Ray 225br. 454 Mercruiser (carburetor, no fuel injection) with Bravo 1 drive. Took it to Avalon, ran great. On the way back, about 11 miles from Avalon, 26 from Dana Point, running around 3200 rpm, it sputters a bit. I lower the rpm, seems ok, take it back to 3200...
