    4.3l mercruiser no start when hot

    When you pump the throttle look down the carb to see if any fuel is shot out from accelerator pump circuit, just trying to figure out if fuel bowl is dry . Thinking fuel leaks down into intake when you shut it off.

    Need better hole shot

    Wasnt trying to correct you. I think with the tighter wot rpm ranges on some engines and tighter peak power bands you will see more props in 1” increments

    Need better hole shot

    That is 100% correct if you are propped such that you can get to the top or just above the max range the boat will have much better throttle response and snappier performance. The revolution 4 is also available in inch increments.

    First startup for the season and then died

    The signature wont show on a mobile device. Check the fuel filter for contaminates, measure fuel pressure, and verify you have spark. The crab style dist caps used on MPIs are known trouble spots, wonder if you are getting arcing inside hence the pop.

Most of our skiing was done behind our neighbors 1969 Starcraft (about 18 ft/ 110 hp merc) and later our 17 ft Sea Ray / 3.0. Both were underpowered to say the least.

    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
