Re: Polaris MSX 150 - IFB
I just acquired a 2004 MSX 150 that hasn't been run in over 2 years. It is in nice shape with 269hrs on it. I would think for a 4 stroke that is about 1/2 life. I am well experienced on Genesis Ficht as I have 2 of them that run great but that is a story right there. I know the MSX is a different animal but does share a few things from the Genesis. Fuel pump is one of them. The guy i purchased it from said it has two issues of won't rev above 3500rpm and won's shut off. So I assume the SIFB is shot. I have not bypassed it yet to see.
Does the SIFB die in sections or completely? It seems on mine, they auto off works because in 2 minutes you hear clicking as stuff powering down and putting the ski in neutral it idles down and doesn't runaway with itself on the trailer.
Has anybody successfully fixed a dead SIFB? It looks like a circuit board attached to a 8 pin Delphi connector submerged in a 1/2 inch of epoxy. Mine actually has a 100uF 16v can capacitor poking through the epoxy. This would be like digging ancient ruins so you didn't damage the circuit board with a Dremel. On mine anyway, the epoxy doesn't seem too hard as I started scrapping away with a screw driver.
I never leave the lanyard in any of my skis so that function I don't care about. I am careful enough not to gun it while in reverse, however, I would like to be able to put it in neutral when trailer testing on the hose so it doesn't over rev. I was thinking of designing a circuit with a 555 timer and a couple gates. I could give all 3 functions back. I would need to think about how to disable the 2 min auto shutoff for DW.
