    Cummins 6bt 5.9-m thermostat replacement?

    Hello All. I have a year 2000 Cummins 6BT 5.9M in a 36' sundeck. It only has 420 hours on it. Runs great, but at 2000 RPM the temp is 190 pushing 200. I have boiled out the heat exchanger, replaced the raw water pump, cleaned out the intake strainer, and all the hoses are good. I don't know IF I...

    Thru Hull Leaking

    Hi - bought a 23' Trophy and the previous owner installed a thru hull in the rear below the water line for the bait tank pump. Well, of course, now it's leaking. It's a plastic threaded pipe sticking out with a plastic cap on it. I want to seal it, and rubber expansion plugs are not working. Any...

    Excessive Fuel Usage

    Hi: We have a 26' 1979 slickcraft (AMF) cabin cruiser with a new 454 raw-water-cooled engine. The boat runs great. However, we seem to be using way too much fuel (gas). A trip from Redondo Beach to Catalina Island is using up over 80 gallons, and that just doesn't seem right at all - it's...

    Velvet Drive Pump-Which Way?

    Against my wishes, my boat partner/mechanic sent our 71C to his auto transmission shop for rebuilding. It came back, we installed it, but it doesn't work(!) Fluid "splashes" around, but it doesn't build any pressure. Tom at Harpurs Marine in Wilmington CA said the external pump by the engine...

    Low Spark, engine is rough

    I've got a GM/Crusader 454 inboard with an original "points and condenser" distributor. The motor runs rough and doesn't produce enough spark. I've replaced the coil and the points and condenser, but it still is not right. I want to upgrade to an electronic ignition...will this likely solve...

    Still Water in Oil

    I've got a 454, raw water cooled engine. Water showed up in the oil, so we first looked at the intake manifold. It appeared that the gasket was breached in a few places so we cleaned out the engine replace the gasket, oil filter, etc. and started it up. IMMEDIATELY, water in the crankcase...

    Water in Oil

    I've got a remanufactured 454 raw water cooled shaft drive. I've been noticing water getting into the carb lately, but didn't think too much of it. I went to the boat yesterday and it wouldn't turn over. We pulled the plugs and water ran out of the back 4 - two on both sides. Because it came...

    Plastic Deck Mats

    I was down in Cancun diving and all their boats at Aquaworld had this thin blue matting that was non skid but allowed you to wash through it to clean the deck. Anyone know where I can get something like it? It was thinner than the Dri-Deck stuff. Thanks :)

    Electronic Ignition

    Hi. I've got another question. This one about electronic ignition. I'd like to put one on my GM 454. I see that GM HEI has an all-in-one unit (not separate box), but they don't for marine application. Anyone know which one I should get?<br />Thanks

    Oil leak from the fuel pump?

    Hi. I've got a remanufactured marine GM 454 in a 1979 Slickcraft cruiser. I'm happy with the motor and all, but the fuel pump appears to be leaking oil. It's on the left front side, looking from the front of the motor. There is a small plug that had a "nut" on it that keeps the fuel plunger...

    Shift and Throttel cables

    I have a 26' fly bridge cabin cruiser with a GM 454 and a velvet drive trans. The shifter is sticking, but not at the trans. I figure the cable is getting bad. Anybody know a easy way to change out the cable without having to tear the sheathing out with it? Thanks.

    First oil change has "dark" oil

    I have 8-10 hours on a remanufactured 454 chevy. The boat is a 26' cabin cruiser. We did the first oil change and the oil is dark/dirty looking. The oil after this change (on the dip stick) is clean. I heard that there is a "poly-something" coating that builders smear all over parts when...

    Re-Gasket a 454 engine

    I have a 1979 26' AMF/Slickcraft cruiser powered by a 454 GM and a straight shaft. We pulled the trans out to rebuild and when the motor was up a few inches, the jack fell out and the motor dropped. Now when I run the boat at 3000 rpm, oil is comming out at the timing chain cover. I've been...
