    SeaDoo Tow Tap

    I believe 6 knots is the Mendoza line where valve is needed

    350 mag guardian thinks engine is running hot but gauge show good.

    First would verify that the temp gauge is accurate with a IR gun on the thermostat housing. If it is not actually overheating likely issue is temperature sensor on port side of thermostat housing. If that was giving wrong temp indication to ECU that would likely cause what you are seeing.

    Hard plane after switch from points ignition

    Cannot be worse than a blown up engine .... seriously if you set it how you outline above you will be ok as you are setting to factory spec.

    prop question

    Depends on how you use your boat. If top speed is your thing yes you don't want a 4 blade. If taking 6-7 people in you boat and going skiing or wakeboarding is then 4 blade can be an improvement in holeshot, stern lift and planning speed. If you have a beamy stern heavy boat like mine I get...

    SeaDoo Tow Tap

    yes seems like any of them need it. I believe it is just a valve to shut off cooling water supply https://jettech.com/en-us/blogs/news/what-is-a-jet-ski-tow-tap-and-why-do-i-need-one

    Trailer axle capacity/sizing

    Agreed my 3500 listed dry weight boat is on a 5200 lb dual axle aluminum trailer. I would not want to go any smaller.

    prop question

    That is the best approach. Get wot rpm numbers with what you have. Likely going to a 19 three blade or an 18” 4 blade will give the results you want with out over revving on wot rpm. I had good luck in similar circumstances with michigan vortex 4 blades. Relatively cheap with good results

    Hard plane after switch from points ignition

    If you can’t get it into base just set the total timing at 2800 rpm or so. not sure what total timing specs are for your engine . Later 4.3 s took I think 24 degrees total so set it around there and see how it runs

    Oil level too high?

    When mixing and matching put the correct amount of oil in and mark the dipstick with a hacksaw. Since you dont know what the correct amount is since you dont know what capacity the non-stock pan is use Scotts recommendation of 3.5" below the rail. Would seem based on what you saw that you...

    1998 4.3 GL Head Replacement

    For sure. Marinas that successfully do this on hundreds of boats are using a large tank with huge amounts of PG, checking for dilution. the avg guy doing 5 gal is not enough run time, and on the hose with cooler water in spring and fall it is tough to really get the engine hot. I do use this...

    4.3 Carb…What’s That Hose?

    Local NAPA has it as well. Probably anyplace that deals with small engine parts and repair does as well.

    1998 4.3 GL Head Replacement

    Yes the 090 M had metric bolts on the starter, side motor mounts, and flyhweel cover. every thing else was SAE... Found this out when I did a 4.3 to 5.0 conversion. to the OP yes easier if it is a non metric block but a metric will work with about $40 worth of bolts. Michigan motorz also...

    Bravo 3 loss of lube oil - slowly then rapidly x2

    I wouldnt be concerned on either. Would look in the housing -if the aluminum casting is scored up or it is really loose with some play you are ok. If it is loose I have staked housings like this to create a raised area to tighten up the fit as a last resort

    Manifolds (Trying to figure out what I am looking at)

    The 140 was to help reduce salt and scale crystallization. I believe the 160 was done to improve emissions. I have a warm manifold that was factory with a 160 stat runs about 170-175 I am I fresh so no real scale issue Personally I would stick w the 160 and use salt away or similar flushing...
