    Mercruiser 3.7 (470) wont turn all the way

    I wouldn't take off the heads just yet. Making more work than needed. It might be fine? Turning by hand is a bit hard to do as there are many moving parts to get to move around. Why not try the starter? Disconnect and ground the coil wire and give it a crank. Putting oil in the cylinders is...

    Engine smell in cabin when boat is tarped for the week (350 i/o)

    I think it's time to shampoo all the carpet, headliner, everything related every nook and cranny to eliminate mold or other strange dirt. Boats are wet no matter how dry they seem.

    Gelcoat cracks around mercruiser transom plate opinions and repair questions.

    Looks like paint to me. If the hull was neglected, some will paint them to make it look nice again. taping around the transom housing the easy way, then add caulk to cover the paint line.

    228 oil pan/timing cover leak

    I hate the 4-piece gaskets, one-piece ones are the way to go.

    new to boats

    Welcome to the site. After three posts you can put up pictures, that would help us help you. Any posts will do. Is there a serial number anywhere on the motor or clamp bracket?

    Corrosion on drive

    Volvo usually does well with warranty stuff. Had a few come in over the years at the shop and things were taken care of well. One was a new pod drive, we had it in the heated storage and one day I noticed a little oil weeping out of the side of the case. bad casting. They showed up in two weeks...

    U-joint bellows ring

    Can't remember the foot pounds of the pins but clean them up well and add a very small dab of red Loctite to the threads. to much and they won't come out again. Just a tiny drop.

    U-joint bellows ring

    Yes, power tune works great. I've bent the ring in the past, now it's easy as pie! I also use it to get stubborn hoses off/on and things like that. Even getting old impellers out of the housings on the bigger pumps helps a lot.

    Mercruiser 3.0 Fuel Issues

    if no one has messed with it, it should be correct. The pump rod pumps a squirt of fuel when you pump the throttle. Look at the holes and see if they are worn or look like it was in a different one before. Nothing I hate worse than someone moving/bending/ and messing with the linkage when they...

    Electric Boats

    A magnet has no effect on aluminum, right? I did the same thing with a copper pipe. Took a magnet, drop it through the pipe, The magnet drops through but rather slowly. It produces an electric field that slows the magnet.

    Temp Gauge Not Working

    Are you sure it's the sender you replaced? Most nowadays have an alarm sender also. The temp one is in the intake before the thermostat, or in the thermostat housing across from the alarm sender. Others may chime in I may be wrong on location.

    Help with identifiing a part on a 350mpi horizon

    Remove the entire drain system, throw it in the trash and drain the block as you normally would. If rust flakes are plugging up that system, you can't be sure the block is draining. It will damage the motor.

    Propane BBQ Grill Repair question

    Yeah, those tubes get spider debris in them, cleaning is all they need most of the time. Regulators seldom go bad, I've seen maybe two over the years go south but they were over 30 years old.

    Mercruiser 3.0 Fuel Issues

    Is this filter before the pump or after?? Regardless it's not coast guard approved. You should have a spin on filter bulkhead mounted before the pump. The pump on a 3.0 has a filter in it already, so another one is really not needed except for water separating purposes. How about a pic of your...
