    Assembling a 4.3 MerCruiser v6 - Parts check needed

    You shouldn't have to disassemble anything - that is the whole point of getting a long or short block. If it is so dirty you need to tear down something is really wrong here. You take it apart I would suspect you void the warranty...if you heard something rattling someone crating it should have too

    Honda BF75 "Making Oil" – Need Help with Thermostat in Cold Climate

    Agreed- sounds like he needs to verify the stat is opening should stay near the stat temp, 120 is too cold in my opinion. As others have suggested making sure you get some higher speed runs it to burn off condensation is a common issue. Does the oil get milky ? IS the level rising

    Easiest Conversion

    this page has links to install drawings of many merc products- any of the 4.3 will have the motor mount locations. The as long as existing stringers are wide enough glassing in mount blocks is no big deal. If they are too close widening them may push you towards the pod.

    Assembling a 4.3 MerCruiser v6 - Parts check needed

    Cast is fine and what is standard in GM marine engines for many years. I believe they were hypereutctic but not 100% sure. Yes there are better pistons out there but bottom line keep detonation at bay and they will be fine.

    Doing a Full Removal 1986 Mercruiser 3.0L 140 hp Engine Question

    i think when I looked at building a gantry when I did mine I think I needed the lifting point to be around 10 ft maybe higher. So 2ft is probably too low. remember the legs have to go under the boat/engine. Depends on how high the gunnels are when you are on the trailer. Have seen folks...

    Assembling a 4.3 MerCruiser v6 - Parts check needed

    Webber & Edelbrock are carbon copies. only diff you may see Merc used a 3 stage step up rod on some of them. Eddy parts will fit. IF you search the threads here you will find some threads where people did NOT find that the eddy jet kit for 4.3s worked well with Vortec heads. I'll see if I can...

    Shift shaft seal on alpha gen two

    Thanks I have the seals (OEM Merc), Issue is I cannot get them to make a seal in the plastic housing (23-815921A20). They have leaked between the seal OD and the plastic, used permatex #3 and let it set up 8 hrs still bubbled on pressure test. The old seal was very hard to get out new seals...

    3.0 tap/knock

    Can tell from the keyboard. It’s making noise so you need to go through and measure all the clearances vs spec. If you don’t have the mI do eters would take it to some one who does

    Alpha 1 Gen 1 oil fill hose

    Mercruiser offered a kit to add the drive reservoirs to gen one drives. Very rarely seen them in service. The 1991 and up gen two had it from the factory. You can run them without. Only advantage is having it if the input shaft seal goes you loose drive oil into the bellows and you may not see...

    It is somewhat common for tach to mess with getting a good spark. If I were in your shoes I would leave tach disconnected put original module back in and test it out
