97 sn pcm chevy proski 5.7L

Hey I'm new to the forum. Has anybody had experience with the PCM 350 5.7L chevy proski EFI TBI engine? I recently purchased this boat and was surprised it had a chevy since most were fords. I've read a few things online about lack of parts and how it is a problematic engine?? I'm going to call skidim in the morning but I thought I would ask since I have limited knowledge. It came with a manual but just looking for insight and experience. Thanks!

Hmmm, are you sure it’s the proski and not the Apex? I don’t think the proski was available until much later. The only thing I see that might be problematic getting parts for is the TBI. But still probably easier to get than the common TBI setup used around 1994-95. Power from the chubby Cheby should be every bit up to par with the other options.

Thanks for the replies. It was a single owner boat purchased new for 24k in '97. The guy that owned it was super detailed and has all maintenance records from new. I thought apex possibly but definately a pro ski engine and I even verified the serial number. I can't find records of impeller change though so that's on my list and I'm thinking of swapping out the plugs for the quick drains. On the starborad side I have a knock sensor I'm assuming and read that it is actually the drain for the block? Wonder how I can hook up a ball type valve with the sensor or if that even doable. Can't wait to get back in the water...6 months of winter has me thinking I need to relocate!

TBI non-ho 351w (94-95) = pro ski. They recycled the name very shortly thereafter on a Chevy that I’ve seen in TSC’s. TBI 350 with proski labels sounds about right. Assume we are talking about a 96-00 boat or thereabouts?
