    PSA for inboard gas owners.....

    I'm buying another, one for the house (furnace and stove are natural gas) and boat (gas inboard)! My boat sits on a salt water mooring all season so I do keep a fair number of tools and such (Tach/Dwell), feeler gauge, point file, plug gapper, timing light, etc). It's a pain to keep bringing...

    I/O (Sterndrive) Conversion to Outboards

    The best beer story: About 20 years ago I was at the Pocono 500 with my son, close friend and friends from work. Typical NASCAR day, few groups on the verge of a fist fight, but mostly calm. About midway a lady near us stands up and exclaims: Oh My GOD, We've Run out of BEER! we all laughed, she...

    I/O (Sterndrive) Conversion to Outboards

    I’d use thicker PVC for a double or triple IPA! Plus add hold downs, you don’t want you beer sliding around down there!

    Fuel came out overflow

    I never fill mind all the way up. The tank is 44 gallons so it’s easy to estimate each 1/4 of a tank is about 11 gallons.

    best muffs to use on mercruisers?

    Agreed I like the genuine Merc ones, I used to use the dual inlet ones from Tempo and others and what I found was the rubber was too stiff to conform to the shape of the lower unit. The Merc ones are made out of much softer rubber. As soon as the engine starts the water quits spraying out the...

    TOPTES PT 520A, $33.99 Amazon tested it with an open gas can and gas stove, definitely alarmed!

    PSA for inboard gas owners.....

    True but if the tank coffin is vented, & there is a leak in the tank (often at the bottom due to water not escaping) that vapor will become apparent sooner or later. You could still have a leak whether or not it's apparent. Alternatively, I think if you have a hatch over the tank like my boat...

    How to run twin 5.0s from portable outboard tanks

    Also, I picked up a portable combustible gas/vapor meter, these can be used to check for gas vapor fumes, as well as propane and nat gas. You might want to check around carefully before doing anything.

    How to run twin 5.0s from portable outboard tanks

    I did that for testing last year, I would also suggest putting a shut off valve on the fuel line between the outboard tank and the engine fuel pump, just in case. Make sure the lines are safely routed as well.

    2005 Mercruiser 5.0L MPI (bravo 3) suddenly started overheating

    What temp is your thermostat? If a 160 it is going to run from about 160 to 175, the latter being seen after you come off plane but it should cool down a little lower after coming plane and idling for a few minutes You can do a few tests to narrow down the casuse: 1) look up the spec for the...

    When/If I have to replace the tank, I plan on adding them, and re-glassing the coffin.

    MCM 7.4 oil

    I'd be interested just to find out what additives are included in the FCW certification for marine oils, that are not in automotive oils, it seems that you can do virgin or used oil analyses and get a lot of information but not about additives. This information is "proprietary" I guess. They...

    Dark colored drive shaft and black looking grease

    For splines I am still using Evinrude Triple Guard which is an excellent great for that purpose, it does come out darker when I pull the drive in the fall but not black. In the gimble bearing and ujoints I use Lucas Marine (blue, same color as Triple Guard) and there the grease stays bluish...

    PSA for inboard gas owners.....

    Certainly true. I think a good idea is for the fuel tank coffin so to speak to have vents on the front and rear bulkheads, that helps also with drying out any moisture.

    PSA for inboard gas owners.....

    Gas fumes are a significant hazard for gas inboard owners. In addition to sniffing before starting up, proper fueling practices and use of the blower, it's a good idea to have a gas vapor detector installed on your boat. I went one step further, I got a hand held combustible gas detector...

    MCM 7.4 oil

    Yep it's not that much money when you look at it that way. I can say after using the Merc Syn Blend 25/50 under the valve covers in my engine looks like new despite salt water use and 6 month storage outside in a damp climate. The engine is often covered with condensation to the point that any...

    MCM 7.4 oil

    That’s what I thought So he’s got some good choices. The VR-1 is a bargain like half the price of the Merc 25/50 syn blend, that’s what I’d use and will probably switch to when I use up the Merc oil I have

    MCM 7.4 oil

    Ok first find out if the engine had flat tappets. If not & you have a roller cam no real issue with zinc. But if you have flat tappets here are some choices: Merc/Quicksilver 25/50 syn blend, I used this and did an oil analysis & it has 1300 ppm of both Zinc & Phosphorus Valvoline VR-1 20/50...
