    Assembling a 4.3 MerCruiser v6 - Parts check needed

    yes that is the correct intake - vortecs always have 8 vertical bolts on intake with the webber carb it should bolt up as I dont think any of them used heated chokes.

    Need better hole shot

    Here is a thread on the rev limiter on an MPI engine. Would assume you feel a miss same as carbed but cannot be sure. Per the thread I believe yours would kick in at 5150 rpm. The crab style ignition caps on the mpi are known issues but usually has a miss. Last summer my neighbors VP MPI was...

    Any Transom experts here. I have a Transom Rebuilding Question.

    drill holes in stringers as well. Usually if the transom is gone so are the stringers. May only be the back part near the transom may be all of them. Would also look at the motor mount stringer and in ski locker if there is one.

    Assembling a 4.3 MerCruiser v6 - Parts check needed

    get the vortecs and a vortec intake for the power gain. Moght as well after doing all this work... I bought a handymans special that PO cracked and did not reuse any of the castings that could have cracked. Just not worth the risk. There must have been some water in there diluting the AF. I...

    What engine other than 5.0 do you have ? serial number if you have it. On a merc the carbed Thunderbolt V systems have a rev limiter too. It will be felt as a miss, you can't miss it... it drops ignition from cylinders then rpm will drop a tad, will keep repeating until you pull back. Dash...

    4.3l mercruiser no start when hot

    that would point more to heat soak on an ignition component. Starting fluid lights off easier Test the spark with an adjustable gap tester when it wont restart and ohm the coil Have you tested spark at plugs, post 1 only mentions spark at coil to distributor. could be loosing spark in dist or...

    4.3l mercruiser no start when hot

    Thinking the fuel bowl is dribbling empty down into intake, leaving engine flooded but carb bowl dry. I get this and hot restart issues on my edlebrock carbed 5.0 ( merc webber same issue), need to open throttle wide to clear the overly rich condition. If it fires on starter fluid would think...

    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.

    Swap drives from one boat to another. How many day project?

    no 5200 otherwise you will never get it off. I think the only place I have seen 5200mentioned is to hold the gasket to the gimbal housing for assembly

    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.

    Need better hole shot

    My experience is much the same skiing was run what you brung back in the day. 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. As mentioned earlier I got decent results on the...

    Need better hole shot

    You may need to go Lower pitch than a 19” , 17 or as mentioned on 4 blades a 16” or 18” vortex . Really depends on how far off wot max rpm you are.

    Replacing clutch on my mini...

    yes Looks good and fun to drive but mechanically they are POS. For us it was an inexpensive used car that my wife loves. At 100 k when I look at the maint that has been done by me or PO it’s ridiculous compared to my last couple other cars 07 camry, 95 volvo 940 , 06 Highlander Hybrid. Done more...
