1989 Malibu Skier


Recommended Posts

Hey Everyone! 

Picked up a beautiful 1989 Malibu Skier last year and it was one of the best decisions i have ever made.  Growing up i was around ski boats my whole life and finally decided to pull the trigger on a clean 1989 Malibu skier with ~900 hours. The boat is in near mint condition, it was owned by an old couple who had owned it since new. Garage Kept and always maintained. Last summer we spent nearly every day on the boat! Clocked over 60 ski days and around 80 hrs. After 2 oil changes and a new impellar we winterized it (After skiing on December 4th in Boulder CO). 

Towards the end of our season, we noticed a slight lag on a few pulls with a slalom skier. Other than that the boat always fires right up and runs strong and pulls skiers right up. Does anyone know what may be causing this? I am going to be replacing fuel water filter and fuel filter before we de-winterize. Also, is there any other maintenance we should consider before hitting the lake? (It is getting warm so might not be that much longer)

I just spent that last two years just outside of Denver, (Pine, CO). Dude, Dec 4th is no joke! I think you're on the right track with the filters. Good luck and congrats on the purchase!

If you haven't given it a tune up (plugs, wires, cap, rotor) that would be money well spent regardless.  If those items don't take care of it, and if it happened only when the boat is warmed up I would try a new coil.  I've gone through a bunch of them.  We keep a spare on board. :)    Lastly the carb, accelerator pump not giving a good shot of fuel?  Floats needing adjusted?  I would save the carb for last.

Thanks Martinarcher! Great advice. Where is the best place to buy parts for the mercruiser? If you have a link for the cap, rotor and coil that would be super helpful!
