    OK to Delay Recommissioning One Year?

    I don't think you will have any issue. My neighbor at the lake is the opposite of me on maintenance- changes his oil every couple years, drops his drive lube if its not milky pumps it back in... he has a 99 bayliner/5.0 2 bbl seems to hold up ok. He doesn't put a ton of hours on it but gets a...

    Mercruiser 305 V8 running hot at low RPM fine at Speed

    that doesnt look like a lot of water at idle. I'll see if I can find the water flow test from merc manual If balls were loose (try to set NOLA up good here...) they would be passing too much water at idle directly to exhaust then overboard. Thats why the lines off the T are cold - they are...

    Mercruiser 305 V8 running hot at low RPM fine at Speed

    If you have the check balls on the thermostat housing they can pass raw water from the impeller right out the exhaust starving the engine. Somewhere in the merc manuals there is a flow test for quantity of water coming up to the thermostat housing. Easy test to do to verify water is getting...

    Lost gearage?

    In theory you can do it your self if you have the merc specific tools ($$), a factory manual, and some decent know how. I think usually if you are paying someone to redo it You end up at the $2k SEI aftermarket cost or the new Merc ($3400) cost pretty quick the gear set kit alone is $600...

    Damp exhaust manifold

    i think normally best to test the manifold by filling with acetone that will wick into cracks easier. Other than that yes two gaskets would only be used if there was a block off plate in between for closed cooling. Would take all gasket material off and file it flat or use belt sander. If they...

    Penn Yan Commander 339 (33') with a tunnel hull

    Any boat that this 20 + years old of that vintage can have stringer or transom rot. a good marine surveyor should be able to diagnose these issues and use a moisture meter to tell the condition of the structure. If you are not versed in this I would recommend a survey , could be the best money...

    Penn Yan Commander 339 (33') with a tunnel hull

    Have you water tested it yet? My grandfather had a 66 Penn Yan Imperial 19, was a nice fishing boat. At that time they made tunnel hull and I/O versions of the same boats. I do think in shallow water areas the tunnel hull can be more popular or somewhat desired. I suspect the inefficacy is more...

    Need help with plugs selection

    It looks like in your other thread you have an 8 bolt intake with 8 vertical intake to head bolts. If that is the case use MR43 LTS. As bondo mentions Vortec is the head type not the block. Given the interchange of parts over the last 68 years on the SBC you can have a lot of mix and match of...

    Lost gearage?

    Thats a gen two would stillgo by bondos comment of getting a SEI drive. i would be worried about why someone sealed the transom housing to transom with rtv and 5200. Usually if that is leaking it is due to a rotten transom.

    Lost gearage?

    This is the best answer. On an alpha gen one or earlier drive without the lube monitor bottle, best to check the lube level frequently. If the input shaft seal goes the lube leaks into the bellows and you will never see it before the upper gear set runs dry. If its in a lift or trailer kept...

    Can you guess how much I paid for all this?

    if stingers and transom are ok that probably fine, if not it is $ 850 too much

    3.0 Mercruiser seems to hang or seize when starting

    As bt mentions veryify battery and electrical connections. Take spark plugs out of engine should spin by hand. If it hangs up might pull the drive as drive ujoints or gimbal bearing could be frozen if it sat with water…. Engine could be corroded too and hang up

    Water Leaking from sides of stern drive help

    Yes those are the idle relief ports exhaust and the spent cooling water it contains will come out when running on the muffs. It wont be even side to side in terms of how much water. I think on my 3.0 it mostly came out one side

    97 Mercruiser 3.0LX will run/won't run

    There's no gunk on yours you can measure it with multi meter set to ohms for your knowledge base. Usually this is related to shifting in or out of gear, worn shift cable will drag the switch and trip it cutting ignition vs causing a quick ignition cutoff/ stumble required to get the dog clutch...

    97 Mercruiser 3.0LX will run/won't run

    You can measure ohms across the switch to see if it closes when actuated How did u zero in on shift interrupt ? If you installed a controller is it tripping the interrupt switch? On water would disconnect it if engine dies and see if it starts as this will kill ignition
