I bought a 2000 Sportstar. The boat runs great and looks great. I am trying to find more info about the 5.0 lit Indmar motor. It appears this boat has the 5.0 tbi motor. Any info would be helpful.

Its my understand only 98 Sportstars had the 305ci TBI motor standard. 99+ had the 5.7L 350ci TBI (aka Predator) used in MCs through 04 model year. If you do a search on Sportstar you will probably find the other thread where people have discussed this model. Here are two I know of, the first Jim&BAWS does a great run down of the model, http://www.tmcowners.com/teamtalk/showthread.php?t=1893

How do you tell if the motor is the 5 lit or 5.7 lit Indmar motor? The flame arrestor is round on the tbi injection. I can't find any other info on the motor. My title has the hp listed as the 310hp but the intake does not look like the predator intake. Thanks

VTCJ is correct about it being standard in 98. From my understanding, you couldn't even get the 5.7 as an option from MC that year (just the 260 hp 302). Not sure about later years. I've skied behind the 5.0L and it seems to have plenty of low end for my needs. I've always regarded the Sportstar as a very nice slalom boat. Very soft wake, too.

Renovator20,

First congrats on the purchase. I really enjoyed my first year last season with the SportStar, I am sure you will to. I am hoping this year gets going soon, cold and rainy here in VT so far.

My knowledge of Chevy V8s is a little rusty at least the 5.0 vs 5.7 specs. I am fairly certain they are the same block with larger bore or stroke to make 5.7L, making an external differentiation difficult. My 5.7L also has the round arrestor and doesnt have the newer Predator plastic cover, however I picked one up on ebay over the winter, I just need to cut it now to fit over my PP. On the lower portion of my block or oilpan there are stickers saying something like Vortex 5.7L that would probably confirm what I think that you have a 5.7L. Not sure what you mean by Predator Intake. Indamar might be able to tell you based on serial #.

98 Was the ONLY year that the 260 HP GM Based 305 5.0 came in the Sportstar. Yours is a GM BASED 350 5.7 310 HP. You have a VORTEC motor that requires a AUTOLITE 103's gapped at 45-60 AWESOME Powe
Upgrade to a CUTTER Stainless 4 blade 13 x 13 1/2 You will love it
