Moomba Mobius V 2000
Indmar 350hp MPFI 5.7L
Had my boat out all weekend and have found i now have an inconsistent power problem.
Boat has been in storage for 7 months, with stabilizer added to a full tank of gas.
Ran her last weekend for 2 days, no problem, started first time, pulled no problem.
Then, this weekend, after 2 days, she started bogging down at 1600rpm... give it more throttle.....just the same, bogging down, white smoke, no power, lots of noise.
Wait 2-3 mins, then off we go again, great......5-10 mins later, bogging down again.
Problem happens with or without Wakeboard-Pro on.
I have added about 80 litres of fuel since initially running, so i am thinking its not water in the fuel.
I changed the fuel water seperator/filter before the first run this year.
Then, i notice there is a kink in the fuel line before the block, AND what looks like an in-line filter, which i have never changed (in 4 years).
I guess my first check is change that filter.......
What about dirt in the carb?
The 1600rpm is wierd......is it at that rev the engine suddenly requests more fuel?
Any help appreciated.
