    gear box oil leaking

    9/10 times it’s 2 stroke oil out exhaust. You’ll soon know if it’s gear oil. It’s horrible stuff and stinks. I’d also suggest that it usually won’t be brown gear oil that’s in the gearbox either. If it’s had the usual quicksilver oil that’s been used.

    18’ nitro 150 blackmax rooster tail or no rooster tail?!?

    Some props throw one more than others. I know a laser 2 is famous for it on light hulls. Same boat with a ballistic….nothing.

    2006 Yamaha SX230 Hard Initial Starts

    Hi. Could be a result of someone not turning the water hose off…before stopping engine, if it’s ran on the trailer previously to launching.

    How is the compression?

    ‘83 Glastron Sx-190 looking for other owners

    Excellent. That a 1.47 ratio alpha ? Quite similar performance to my bowrider. Yet to find a prop that will let it hit 70 and still be half decent at low down acceleration. Almost gutless down low with any serious pitch. Usually run a compromise pitch that will see into the 60’s…but still...

    High RPM, little or no acceleration

    From the title…I’d guess the prop(s) hub is away…or your outdrive has water in the oil or the wrong oil…and cone clutch is slipping.

    ‘83 Glastron Sx-190 looking for other owners

    Be faster than enough for most…I’d guess. I’d guess she won’t be far from 60 at least ?

    ‘83 Glastron Sx-190 looking for other owners

    Sure looks as if she’s plenty of power there ! Nice. I’ve got a lovely old cvx16 with a 150 merc. Quick machine. Love a classic glastron

    4.3 Carb v 4.3MPI

    I get what you’ve said there…but this maxum with the carb was a vortec engine with 4 barrel and manifold. Started off as a 250hp model previously. I’ll concede that it was through an alpha 1. The mpi was through a bravo 3. Anyway. There was a fair difference I thought. The carb and alpha could...

    Need prop help with new boat

    Yeah. I’d ask what prop is on it now. Something ain’t right. Will be a prop issue or a running issue for sure. What rpm are you getting when you are in the 40’s ?

    4.3 Carb v 4.3MPI

    To be honest. Apart from a few diz caps and an IAC…mine has been faultless. 700 hours later. Sits for long periods unused. Always starts right up. I think it’s all about how you look after them. As with any. Oh. Had a shift interruption fault. But not the fault of the mpi. Common to carb too...

    Rerouted fuel line...too much to lift?

    Is the fuel line primer bulb going the right way ?

    Prop for hole shot water skiing

    Hi. Not a fan…but there likely isn’t a better prop for doing this, than a hi 5 prop. You’ll lose top end and efficiency over a 3 blade…but they sure do a great job of pulling people out the water. If that’s what you want to do 90% of the time…get one. But being fussy…I’d ask what pitch you have...

    4.3 Carb v 4.3MPI

    The 5.7 carb hasn’t got more power than the 5.0 mpi though.

    4.3 Carb v 4.3MPI

    Were they ever fitted in a boat from factory? Always thought they were after offered quicksilver things. Hp rating always seemed more that original versions. No idea why.

    Regal 2100 sometimes take long time to speed up to reach 16 miles it’s look like struggling on between 10-15 miles but once hit 15 miles it’s will go

    Have a search on here for mpi distributor cap.

    Regal 2100 sometimes take long time to speed up to reach 16 miles it’s look like struggling on between 10-15 miles but once hit 15 miles it’s will go

    The distributor cap and rotor. They are by far the most common cause of issues like this. Notoriously famous for failing. It’s the flat cap spider looking thing on your engine. Terrible thing for failing and gathering moisture at least. Also often cross fire amongst the electrodes too.

    Mercury 175XR2 Sports Jet Pison Crown Melted

    Are you still running with the oil injection system ? Suspect for me

    Regal 2100 sometimes take long time to speed up to reach 16 miles it’s look like struggling on between 10-15 miles but once hit 15 miles it’s will go

    Hi. I think you’re going too deep into this perhaps. That looks like a 5.0 gxi. Hate to rattle on again about this..but have you replaced the diz cap yet ? 100% the most common cause of issue on these engines.
