Hi all, my buddy just bought a late 90's sportstar with a 5.7 LT engine in it. Wondering what spark plugs go in it. Any ideas?

AC Delco MR43LTS. The pic is from the Indmar manual for those years.

Thanks for the info. Does anyone out there have a 99 Sportstar owners manual in PDF they could share with me?

Thanks for the info. I have found the red hose going to the engine for fuel. There seems to be no inline installed and I guess the filter is under the floor at the back behind the seat. Can anyone verify this the manual is unclear.

Thanks Guys.

Still looking for the fuel filter. Followed the line all the way back to the tank and no filter. Where is it??

It more than likely has an in tank fuel filter on the bottom of the fuel pump module. It's not a maintenance item so just leave it alone unless you're having known fuel delivery problems.

If it is a TBI engine, fuel filter is attached to the fuel line, near TBI fuel pump. Looks like the:

According to skidim the in tank filter was used in late 1999 and up models. I believe the manual recommends changing the in tank filter every 100 hours. If you plan on changing the in tank filter, you will also need a new gasket and probably a new set of the bolts with gaskets on them. I bought all the stuff to change mine this year, but I'm trying to wait until the boat is really low on fuel to change it. I tried doing it with the tank mostly full and it did not go well.
