PCM Excalibur 330 in a Barefoot nautique

+1 if your using the 1.23 trans

I highly doubt it..

Exactly how did you locate the engine in the boat... 4 inches is a lot of movement forward?

Ben#155 wrote: Yes this helps, thank you!I cant get the bolt out of the lower mounting, so i have to remove the whole mounting first.

Most welcome. I had the aluminum and a stainless bolt; your pylon must be under tension for it to be stuck?

Leaving the obvious alone...   

Wow, that's almost a million! I went out for a look; you'll lose a little leg room for the observers and have a tighter passage between the doghouse and the captain's chair, but it looks doable.

The lower pylon mount should be an aluminum plate with a collar/socket welded to it for the pylon to fit in. The plate tabs are what's glassed in. I'll look for a pic.



This will help?

FWIW-I did a good job with the pylon base, but don't follow what I did here with the bilge pump pad. My stupid human trick here was to put that plywood in upside down. I had to cut it out and re-fit to get it lower.

How far forward does the excal need to go? Would it be possible to shorten the engine end of the shaft a little?

Little update;

Engine is rebuild now and has run. These engines has nice camshafts! They sounds very nice! I hope that i can swap the engine in a couple of weeks,
I still need an other prop. I think it will be useless to try my currently 13x13 prop.

The last year for the Sport hull was 2002. You were most likely in a 206 or 216 (the latter is a larger boat by 6" and 400 lbs). Unless you verified the prop, thats a question mark as well.

Yes, thats true... but the heavier boats will be propped accordingly. You can put a pretty small engine in some of these boats and they'll still come out of the hole like crazy with the right prop. My buddy's 3000 lb Shamrock with a 302 comes to mind- that thing jumped out of the hole with a 13x10.5 on it. Most people using the boat that way are unconcerned if you run out of RPM (rev limiter) before you hit the 40mph mark. Propping for all around performance (holeshot+top end) is a bit trickier. As far as GT40 vs. Excal goes, the difference isnt huge, but its definitely measureable. Both are great motors though.

CQ, I think you mean most direct drive CC's with the Excal got the 422, which is mostly true... I know that was the stock prop on the 196 and 206. Not sure if the 216 got a smaller wheel- and I know the 200 got a prop with less pitch when mated to that engine.

I do think the 422 would be a good starting point for the relatively light BFN hull... but everyone's use varies!

I'm glad I drove a friends 2003 Air Nautique with the 330 about 3 weeks before I got my Air Nautique. We were pulling 5 kids on wakeboards and wakeskates at one time. The 330 took a hair shy of wide open throttle to get them up. Then later the same day, me and three friends were behind another friends moomba with the 330, I didn't think it was going to get the four of us up. I couldn't believe the difference the GT40 has on the bottom end.

the only way your up this early is if you stayed up all night

I don,t have any experience with one of these engines (in ski boats), only with older non feul injected Ford and GM, these engines have almost the same performance.

The 330 might have good top end, but it doesn't pull out of the hole like a GT40.

Do you have one on hand already, or are you buying new?

What are you going to use the boat for?

Witch would be the best prop to start with 12.5 X 15 ?

yes that would be my first option
