    Impeller replacement glycerin and grease

    Both Volvo and Mercruiser call for their own grease, and it seems each call-out is a different type of grease. :rolleyes: I have used a single marine grease for everything with no adverse effect. On impeller case internals if often use dish soap for the initial break-in.

    I/O (Sterndrive) Conversion to Outboards

    Yes . . . lots of bolts. The 'glue' is more of a water-tight sealant. . . :LOL:

    I/O (Sterndrive) Conversion to Outboards

    It gets worse . . . Would you sell just the engines? (no . . . they don't work without the controls and wiring) I'm a Merc Tech, I know this stuff . . . (no you don't) How many hours? What year? (the listing has all the info) I just need the throttles . . . how much for those? (same price as...

    I/O (Sterndrive) Conversion to Outboards

    Weekend Update . . . A belated Happy Halloween to those who partake in the festivities. I will be back at the outboard conversion over the next few days. Some fiberglass supplies arrived yesterday and more stuff is arriving today. I've been cleaning up the engines, outdrives, and other...

    I/O (Sterndrive) Conversion to Outboards

    Having the transom scooted out the 20" from the bunks is actually helpful in verifying some of the measurements. I got one of those digital protractor thingys so I could measure the various angles. . The transom is 12˚, which I sort of knew from the drawings I got. Mercury recommends a 14˚...

    I/O (Sterndrive) Conversion to Outboards

    Today I played trailer moving games . . . I want to see if I can get a decent balance point & manageable tongue weight. The boat was about 6" off-center (to port) when we pulled the boat out of the water. So that was the first order of business. Once I got the boat lifted up in the air, I...

    I/O (Sterndrive) Conversion to Outboards

    The Mercruiser engines new are around $23K each, new SeaCore outdrives are around $10K each, the transom assemblies are around $5K each, the DTS & Axius is hard to say, but figure $10-15K. So all new would be around $90K . . . 20% of new price would be $18K . . . 30% would be $27K. So, I...

    I/O (Sterndrive) Conversion to Outboards

    I was quoted $10K as a 'trade-in', so I'll be selling myself. I hope to get more than the $20K, but that is what budgets are for (less optimistic).

    Cruiser comparison

    I've had surveys done on all 3 of the power boats that I bought over the years. I try to look for surveyors who have a partnership with a marine mechanic, as that makes the process easier. Basically getting it all done at once. I usually search through boating forums for surveyors who have...

    I/O (Sterndrive) Conversion to Outboards

    My total budget is $84K factoring in getting $20K for the sale of the Mercruiser engines. Ideally, I'd like to get a wee bit more for the engines, but it is hard to tell.

    I/O (Sterndrive) Conversion to Outboards

    Budget check . . . Currently at $4,109 vs. my budget line of $6,000 for the engine removal and extension pod construction. More than I thought, but the bulk of the stuff is purchased.

    7.4 GS (1998) DP Idle Fluctuation, Specific RPM range

    2 thoughts . . . 1) You really need the computer diagnostics to troubleshoot a fuel injected engine. 2) If I had to guess, I'd be looking at the throttle position sensor.

    Ordered a gallon of the SmartStrip . . . It seems to work well.

    Solar charging batteries

    Should be 3.2 volts (nominal), which gets to the battery spec of 12.8 volts. Fully charged the cells would be around 3.6 volts each. The cell voltages are quite even, just low.

    I/O (Sterndrive) Conversion to Outboards

    There is a marine version of the SmartStrip. . . . In other news . . . I got the engines cleaned up . . The Coosa Board was delivered. . Maybe time to verify my measurements and think about the details of building the extension pod. :unsure: :D

    Solar charging batteries

    I am not hopeful for those batteries. Fully charged, the resting voltage should be in the 13.5+ range. Anything in the low 12 volt range is almost empty (about 12% charged)

    I/O (Sterndrive) Conversion to Outboards

    I'd rather not sand toxic paint. Prefer a liquid/gel type of remover.
