    Mercruiser 188 Open Cooling System

    yes thermostat must be open but if it were me just drain the block and associated systems vs running AF. If really want to do AF to do it right you need to drain it first otherwise too much risk of diluting the AF

    Mercruiser 188 Open Cooling System

    Most of the free sites get shutdown for (understandable) copyright infringement. Best bet is to determine what manual number covers your engine and look on ebay for a used copy. this is for the 351 version but I think has the diagram you are looking for . you have to expand the window to see...

    Looking for a different distributor than my crab cat dist.

    You seem to hear mixed comments on pertronix componenets. Why not get a used TB distributor as BT suggested? Seems simplest solution Additionally can you just put a nut on the backside of where the thread is stripped? Maybe not the most elegant solution but it cap just has to hold the cap on

    Bravo 3 Engine Alignment

    Yes work on the alignment -you should never have to pound the alignment bar in. What do the witness marks of grease look like? that is key to know if you need to move the front of engine up or down. I would look through the gimbal into the coupler as you may have damaged it pounding the bar...

    4.3LX & Weber Carb Service

    The fuel coming up and dribbling off of boosters is evidence of float bowl overflowing bad or misadjusted needle and seat/float, or too much fuel pressure. Until engine is running fuel pump should only be running when starter is cranking. Get a good carb kit from a place like mikes carb and...

    1986 Mercruiser 470/170hp/3.7L Carb backfire, low vacuum, other weird issues

    what about it is not rebuildable? Willing to bet that with some guidance you can properly rebuild it. anyone here who says they haven’t re-rebuilt a carb is FOS… my success rate improved by getting a ultrasonic cleaner from harbor freight used it with both carb cleaner and also simple green in...

    1986 Mercruiser 470/170hp/3.7L Carb backfire, low vacuum, other weird issues

    That is on old holley power valves not Rochester derivatives. the newer holley power valves are not susceptible to backfire damage anyways .

    1986 Mercruiser 470/170hp/3.7L Carb backfire, low vacuum, other weird issues

    normally those are a tight fit between baseplate and throttle shaft. When restoring carbs some better rebuilders will bush the throttle shaft to seal. On a new carb this should not be send it back and rebuild the oem carb or have it rebuilt by someone competent. This is the rub with these...

    The block is cracked- Doesn't matter what oil pressure is. Pull the engine get a new long block and manifolds. I did a similar repower on a 04 Sea Ray back in 2016. I ended up getting a new (not reman) extended base engine from Michigan Motorz. of course it was more money this way but just...

    I put that kit on my trailer back in 2015- dual axle Magic Tilt - just under 5k total weight. I don't tow that far or that often, only had one issue where I pulled the boat at end of season and the pads were rusted to the rotors (trailer sits outside during summer) , so good thing they switched...

    installing a remote oil filter set up, got a question....

    I think we had a thread on this.... What bypass are VP and Merc using in their OEM setup? if there was an issue with that someone would know, would also think MM would know as well.

    40 HP Johnson, just tilt or tilt/trim?

    I would think if they are calling it tilt and trim then yes you can trim with it. There was a note on the parts page you listed Power Trim/Tilt "F" Model Number Suffix Only do you have that in your model number?
