    Differing exhaust riser temps

    New remaned 4.3l in my 2001 Stingray w Alpha1 ​IR temp on port side top of riser after getting engine up to operating temp was 190 and starboard 95. Preliminary research online seems to indicate the normal difference is opposite of what I have, correct?

    Power washed my new to me 2001 Stingray CC today and the forward storage boxes filled with water even though they have corner scuppers that drain with hoses thru the side of the boat just above the water line.

    early edition 4.3 efi ok?

    I am considering purchasing a 2001 boat with a 4.3L v6 that claims it is efi, ​When I physically inspected the boat, it seemed to me to be a 2barrel carb with what appears to be add on injectors over the butterflies, I assume this is an early version of fuel injection. Should I be concerned?

    Short in the silent choice exhaust?

    Recently purchased a 1999 Powerquest with a single 454 mag mpi that has silent choice exhaust. I noticed that the amp meter on the dash reads just over 12 volts when in loud exhaust mode but under 10 amps when the silent option button on the dash is toggled. What should I do?

    search function

    It used to be that I could do a search within a specific sub category (ie Mercruiser i/o) but the only search I see now is way up at the top of the page and using it only leads to frustration as it gets results from other categories that I am not interested in (ie outboards) Oddly enough when I...

    Different winterizing question

    So I have been lurking here for a few years, been listening to Don S insist that air don't freeze, so I decide to take the plung this year and not bother with the red pop anti-freeze for the first time. By the way, for those that are new, Don and this forum have saved me thousands of dollars...

    Problems after running aground

    I can't believe I ran a ground in the middle of Lake St Clair. Was coming back in at 30 MPH and ran around, almost knocked the wife out cold as she hit the front when we came to an abrubt stop. Everyone got out and we pushed it out deep enough to get underway again. About 1 mile later I...
