    Prop ventilation?

    I talked to a prop shop today because I’d read that getting a four blade prop as opposed to the three blade I have now could help with the prop ventilation. He told me to try bringing the trim up as I get up to speed (which feels counter intuitive) because it will make the prop dig in as low as...

    Prop ventilation?

    1978 Stuery 17’ 7ft beam tribulation Johnson 115 2 stroke. Boat does fine working it’s way up to speed, when it hits around 4,000 rpm and getting up on plane the motor starts racing up to 8k rpm and the propulsion decreases significantly. Is this prop ventilation? If so, what can be done to fix...

    Cooling and compression quandary: 1982 Johnson 115hp Sea Horse

    I bought the boat used, took it out and the heat alarm came on after running it at some higher rpms. I promptly turned the engine off, waited forever it to cool and could not restart the engine and got a tow in. When back I did a compression test (cold) and all four cylinders were around 90psi...

    What is this switch for?

    Thank you for your response. Which position should it be in when starting the motor using the key and battery?

    Volvo 280 tilt mechanism

    I have a 1979 19’ Bayliner with a Volvo Penta (Chevy) 350, and a Volvo Penta 280 Outdrive. The person I got it from had a mechanic disengage the outdrive from the tilt mechanism. The (worm drive) tilt motor likely needs to be replaced, so in the meantime e he wanted to use the boat. I am...

    Volvo Penta 280 rust colored stains

    I’m thinking about buying this boat with a 350 Chevy. One thing is the outdrive has a rust colored stain around it (pictured) Does anyone know what is causing this? The exhaust maybe? Could it be that the manifold risers are corroded on the inside and are spitting it out? thanks in advance.

    Is this a powerpack?

    I've been going through my 1981 Starcraft 16ft. Aluminum boat (1981 Evinrude 90hp) and finally got to testing the power trim, it appears one or both solenoids are out and there is general corrosion so it's time to replace the whole shebang. So I showed the guys at west marine the attached photo...

    Electrical Misery

    Went out on the ocean this morning and got stuck, when turning the key I just get a click then there is no juice going to gauges at all. Bought a new battery, still the same problem. Put an electrical tester to the starter and the ground and it shows current. Now my motor and outdrive are full...

    Ticking sound: gimbal bearing or exhaust flaps?

    1989 Mercruiser 4.3 Alpha-1 outdrive. Hearing a ticking sound at low rpm's, haven't noticed a growling or ticking sound when running in water at higher rpms or if I turn hard. One mechanic says it's the exhaust flaps, another says it's the gimbal bearing and the outdrive needs to be pulled...

    Want to find or build a top for my boat, any ideas?

    Okay, before someone says "Hey idiot, you can find bimini tops here on the site" I just want you to know that I already know that. So, I have a 1963 Glastron Gulfstream V194 and want to either buy, or make a hard or soft top for it. Obviously, it's kind of a hard thing to find. I do have a soft...

    Rookie painting

    I have a 1963 Glastron Gulfstream V194, finally got it running well so now is the time for some cosmetics. Some of the white paint near the bottom of the fiberglass hull towards the bow is flaking/peeling. This is not going to be a designer boat so I am looking for the most cost-eficient way of...

    Many times when I try to start the (electric start) motor the shaft that is supposed to pop up and engage withe flywheel doesn't come up and just whirs. Is this the solenoid failing, so I need to get a new starter or can this one be repaired? Thanks in advance for any help. James

    Motor stalling 1989 Mercruiser 4.3 V6 175hp

    Boat starts up fine in the water, for the first couple of minutes I can get it up to about 1900rpms before it wants to crap out. At first, i can sometimes get it to "surge" if I give it a lot of throttle, then eventually, not at all. Then, upon starting it again I can only get slightly above...

    Runs great in the driveway, not so much in the water - how not to buy a boat

    I just bought a 1963 Glastron Gulfstream with a 1989 Mercruiser V6 4.3 I/O. It ran great in the driveway and me being the *GENIUS* that I am decided to buy it without doing a sea trial, especially since the guy advertised the boat as 'TURN KEY", and hey, he seemed like a really nice guy...BIG...
