    1993 Mercruiser 4.3 v6 temperature sending unit

    I am assembling 1993 mercruiser 4.3 v6. I had a block with heads and to get accessories I bought an older 1986 Larsen with 4.3 v6 engine. However there are some differences. One of them is the location of the water temperature sender. On the newer engine it is in the thermostat assembly, and...

    Mercruiser 4.3 v6 Oil Pan installation

    I looked at the manual for installation of the oil pan with a new gasket. It says to use some RTV gasket silicon at the oil rear seal and the front timing cover at the joints. I wonder if this silicone should be put under the gasket or between the oil rear seal and the block and between the...

    1993 4.3 v6 rocker arm support

    Im rebuilding this engine, 1993 4.3 v6 GM. I noticed that 2002 4.3 v6 has a rocker arm support piece that goes under the rocker arms. However the 1993 block does not seem to have any support. Or is this part just missing, since the heads for this block I bought separately and the previous owner...

    I just got a new timing cover (plastic one) for 4.3 v6 vortec mercruiser. It looks like there is a seal already installed n the groove, but the cover came with gasket maker little package. I tied to look at the Seloc manual but it is useless. So, do I need to use the gasket maker with the...

    Building an engine test stand

    I realized that it saves a lot of efforts and time to test run the engine before installation, after I got one installed with a bad rear seal. Cursed all the way removing this engine. It started leaking about after 30 mins of running in water. So I decided to build an engine stand, with a...

    Oil Pickup and oil pan from automotive 4.3 v6 in marine engine

    Im trying to rebuild a 2002 vortec chevy 4.3 v6 to make a marine engine out of it. Got the marine rebuild kit, marine camshaft, intake manifold for a 2bbl carb with mercarb. Now, the oil pickup in marine engines is much bigger than the one in the automotive. I can buy a marine pickup for $20...

    I am rebuilding 2002 Mercruiser 4.3 v6. I started with freeze plugs a while ago and was waiting for the rebuild kit.

    cracked exhaust manifold on 4.3 v6 mercruiser

    I started the engine Mercruiser 4.3 v6 on the boat I recently purchased (1985 Larsen). The engine (at least some parts of it, not the block itself) and outdrive I was going to put into my newer 2005 Larsen boat, which has no drivetrain. So this engine appears to run (surprisingly since it was...

    Adjusting trim level and trim limit senders

    I recently changed the bellows on my Alpha one gen 2 outdrive. I put the old trim limit and trim level senders. However, looks like they require adjustment since the trim level gauge does not show the outdrive movement, it is stuck in the top position. I looked online for the sending unit...

    Im rebuilding this engine (2002 or so Chevy 4.3 v6 vortec block) and in my prior rebuilds I used the machine shop when installed my camshaft bearings. It was a $50 job that was done in a day or so, but recently I purchased the bearing installation/removal tool and decided to try it myself. I...

    Restoring 1988 shoreland'r trailer

    I bought a 1985 Larson boat to get the engine, transom plate and the outdrive. The trailer looked king of old and rusty on the picture, so I was just going to either donate the boat and the trailer to anybody who wants it. But upon closer inspection, I realized that the trailer is a Shoreland'r...

    I changed the speed sensor a couple years ago, since it was not working all the times. It worked on the start, first several minutes and then was showing speed intermittently. I bought an aftermarket replacement part (i believe it was a new one) but it showed he same behavior, works first couple...

    measuring and cutting the material for the boat bow and rear covers

    Another one of my boat covers fall apart as a victim of the sun, rain and wind. And this was a more expensive one. So I decided to make a bow and a rear enclosure snap on covers. I have a roll of sunbrella material, and a good walking foot sewing machine. I measured the boat sizes for the cover...

    Man, this is such a pain in the neck! I was going to replace the gear lube monitor hose in the bell housing, but since it required complete gimbal removal, I decided to replace the bellows and the bearing as well. Took me almost 6 hours and still Im not finished. I struggled mightily with...
