PCM also had a base and HO BBC, they were rated 330 hp and the HO was either 390 or 425 hp depending on who wants to tell the story. The base engine was RH while the HO was LH. I'm guessing both Indmars were LH so tough to tell w/o tearing into it.

425 hp/454 ci is really pushing it for a stock production engine.

Thats what I was thinking Hollywood. 330 on base, 4 and change on the HO. Good luck convincing them of that...

State Farm wanted double what I am getting using Ski Safe via Geico. I think the Ski Safe policy is much more robust as well.

CMW,

There were two 454's. Both were 7.4 litre. One was coined an HO. Here are some specs.

Both the same
Displ. 7.4 / 454 CID
Bore & Stroke 4.25 x 4.00
comp ratio 8.8:1
Block GM
Fuel Sys Holley 4 barrel

Not the same
RPM HO version turns 200 more per min. @ 4600
HO was a left hand rotation only.

Net weight of engines are identical.

Voyager Marine Ins. underwritten by Progressive has been a great deal for us with no layup.

I don't need to be convinced, my insurance company does. I am being charged for 475hp motor right now for a boat that will probably never go above 40 mph. If your thinking I want to impress somebody, I would have bought something besides a 19 year old boat. TMCno1 had brochures that stated 325-375hp. This is why I question it. I am quite happy with the power of the boat. I am 6'5" 210lbs and it will get me up quick. I am not a spring chicken and have back issues from years of abusing it, so the faster I get up, the more I can ski.

I do appreciate all the reply's about insurance. I have already gotten some cheaper quotes. None of them asked engine size. I hope this will not be a problem when they check out the hull identification number.

I think everyone in this thread is trying to help you. I didn't see TMCno1 post in this thread but 325-375 sounds much more reasonable. Now I'm wondering if 425 was just a 325 typo somewhere along the way (not just this thread). I also noticed Jim@BAWS failed to throw out HP numbers...

I'm hoping you are right. I am just wondering if I am paying more for insurance since they rate it at 475hp. I will be making some more phone calls this weekend and find a better rate. I just wish I had a way to prove it is not 475hp. I am not sure if the HIN denotes this.
