Hey guys Im new to this forum I just picked up a 2006 Sugar Sand it’s a 16’ Merc 2.5l 240hp powered jetboat #0e428322 it was only used from 2006-2008 on a fresh water lake and has been sitting since (10 years!)… What I have done so far
Detail
Battery
Inline fuel filter 35-889615
Fuel water separator 35-18458 4
Float needle
Cleaned vaporizer out
Sparkplugs
Starter
Drained fuel and filled with 30gallons of 93 octane with an additive to help remove water if any
Topped off oil tank
Replaced radio and speakers
Hatch pistons
1sttime we cranked it she fired right up connected hose sounded great charging at 14.2 volts we put her in the water and ran great all day ¾ of the tank down thought all was well dropped off one of my buddies which involved a 10 minute 5mph zone after he jumped out I went to take off and it started bogging, pulled back and it ideled fine went to accelerate slowly went right up on plain then died again. limped the boat home and it has been sitting on my lift for 2 days went to check it out today brought a 5gallon container of fresh fuel figured id try and run everything I could out of it and top off with fresh. So just now I take off and all is well for 5 min then she dies again. It will run all day at 4k rpm no problems but when u accelerate she boggs out. I was able to run it dry of fuel and topped it off, while I was out there before I started it I noticed the alternator belt was broken off please let me know where I should start checking or replacing
It’s a 30ish gallon plastic inboard fuel tank with no bulb I have not replaced any fuel lines just yet
