Boat US said an insurance policy is void if the engines were modified but I explained to them that the HP level of the modification was less than the mfgr offered in new production. While I'm certain this is true I can't find any documents to support my explanation. Does anyone have any paper that shows what Formula offered for power options in an 89 357 SR1?

My strokers are modified 420's to only 500HP and I have seen something that showed Formula had power packages higher than 500HP back then but I don't remember where I saw it.

Can anyone help on this or do I need to get something from Formula?
TIA

aquaforce there is a performance sheet on the 357 in this thread.

Excellent! That is what I think I saw before but I couldn't remember where. I looked on Formulas site but as said before those power options don't show and it says to see a dealer. Can't really do that now can we.
Thanks a lot. I will print that out and put it in my file. That way if BoatUS has anything else or different to say I will have something for them.
Thanks again.

Those Formula numbers are right on with what my boat is doing according to the PO. These are stroked and maybe why I have +1 on the MPH.
