    I/O (Sterndrive) Conversion to Outboards

    Is that between $75-$100k of outboards out back?

    Conversion from I/O to outboard on Islander.

    If you’re in freshwater even though I have at times cursed the work that I/Os require (salt water use and moorage) I would not get involved in a project like this. With an I/O the 2 options that would make maintenance easier to deal with are a remote oil filter mount & closed cooling. The main...

    Mercruiser power steering ball stud

    Glad it worked well. Beats paying a grand for a new one like some Volvo or Merc owners wind up doing.

    I have a question on a volvo penta 7.4 engine

    I would do 2 tests: pressure test with HE installed, you can have leaks from other places, hoses, front water pump, core plugs, etc combustion gas test, to see if combustion gas is getting into the AF. even though the HGs were replaced, unless the cyl head bolt holes were carefully cleaned out...

    I have a question on a volvo penta 7.4 engine

    agreed you need to do a cooling system pressure test and also make sure that combustion gas isn't getting into the antifreeze, this can over-pressurize the system and cause it to lose antifreeze. Cause is usually a leaky head gasket hope it's not that in your case. in addition to testing the...

    How often do you change your bellows and shift seal?

    I have had bellows last as long as 10 years even on a boat moored in salt water. I do carefully inspect it when the drive is pulled each season and will replace it as soon as I see any signs of cracks in the rubber between the folds. That strategy has helped me avoid expensive repairs. Think of...

    mercruiser 4.3 thermostat housing

    When I did that job, the main thing I recall was trying to keep everything lined up. So some Permatex Aviation sealer on the water port part of the cyl head will hold the gaskets in place while you carefully lower the manifold in place, then hand thread in the 12 bolts and torque to spec. If you...

    they look good too. Does Summit ship to Italy? PS they are way cheaper than the ARP, I think I paid about $85 USD back in 2017.

    mercruiser 4.3 thermostat housing

    Sorry don't know the company, but the main thing is that the threads are nice and clean. As long as they thread in well, they should be OK. Make sure to follow the torque spec pattern, etc. Since some of the bolts bottom out in a cooling passage, I used Permatex Aviation on the threads on mine...

    That is correct about the ARP bolt torque specs, I used theirs not Merc's or GM's. The GM spec is 65 ft lbs, the ARP was 70 ft lbs Torque for the intake manifold bolts on the Pre Vortec was 30 ft lbs

    remember yours is a Pre-Vortec, the Vortec started in '96, so make sure they know that, the bolts could be different as well as the torque specs.
