    4.3 diesling

    I've used it within the last 10 years so the technology still works... Decarbonizing definitely helped on my 3.0, I did this with seafoam (Water, seafoam, or GM top engine cleaner all work well), I also fattened up my idle mix a bit. is your engine running cool as if it is hot sure to impeller...

    Fuel tank suction tube removal

    Funny you say very fine hair, when i emptied the filter into a container you could see something that looked like texture in the gas moving around, almost like layers of gel. Then when it sat after five minutes it was milky… I ran it on a remote tank yesterday with same bogging, so assume carb...

    Running temp for 3.0 tks mercruiser suntracker 27 ft pontoon?

    Yep just fine exactly what my merc with a 160 stat runs at, even in cooler water. I don’t think the alarm for overheat trips until 200 or 205.

    Manifold/riser 3.0 mercruiser

    That’s smart to do before getting in too deep. the compression numbers are perfect on two and serviceable on two, so probabky would run. If manifold is freeze cracked was it not winterized ? on a good note if it’s completely roached, you can probably find a good used take out 3.0 for...

    I have a leak.

    No if the studs were changed out and were longer and nuts bottomed out but changing a ss for a steel one isnt going to make a chit of a difference

    I have a leak.

    might retighten the transom housing bolts as a sanity check and exhaust pipe. Maybe something simple like shift bellows.

    Manifold/riser 3.0 mercruiser

    it would leak back through the valves and past the rings, but wouldnt think you would see that until after shutdown. Thera re could have been residual water as usually it takes a couple of changes to get rid of the milk. I would pressure test the cooling system with out the manifold or block...

    Knocking when turning

    Only other thing I could think is the orings on driveshaft are getting hub=ng up on gimbal bearing or not greased well. I had a hell of a time one time when I forgot to grease the orings. Also when turning the prop was it locked in gear CCW? otherwise it will pop out of gear and you think you...

    I have a leak.

    boat with engine is probably deeper in the water as well. You will need a scope camera to see wtf it is.

    Merc Alpha One trim/tilt Q (feeling like a newby)

    100% yes you can do it, as mentioned with 3 boats over last 40 years in same shallow cove … no issues unless at full up and higher rpms you will hear the u joint knock

    Merc Alpha One trim/tilt Q (feeling like a newby)

    I have boated for years (40+) keeping my boats on a lift on a shallow cove (25" deep at dock). You are just fine running the boat at idle /just above idle speeds in the trailer position. Just keep the engine speed below 800-900 rpm. I have to idle out about 5-7 min to get to deep water, so my...

    No oil on dip stick after adding 6 liters

    I would not over fill it but also would take dipstick to dealer and see if they can compare length as something is wrong here. You may be able to find a universal replacement dipstick that hits the oil level

    Knocking when turning

    pull the drive see if the gimbal is fully seated, if not seated drive it in more. if seated replace u joints. my ujoints felt fine but when I changed them you could see wear on the crosses What drive do you have ? generally you can get a ujoint from an auto parts store vs paying the ridiculous...

    No oil on dip stick after adding 6 liters

    worth checking it is all the way down - also worth checking do you have the correct dipstick. Are you in a hoist , the water or on a trailer? willing to bet that the angle of the boat is affecting your reading. Not sure if there is a drain hose on the pan or suck up only ? if you can drain it...

    Oil, pressure safety switch

    these guys may have one - https://www.partdeal.com/ i got a sending unit for my 65 GTO that had a different ohm range so I could make my factory gauge read 0-80 psi vs the factory 0-60. Had a good collection of senders/switches. They had some Hella units which are good OEM quality. Didn't...
