!989 33' fountain w/ TRS drives and 420's .Thanks

[BAJA WILL]

I am going to guess 70ish but not real familiar with that boat or set up

[GS42fun]

You will be right about 72 mph.

[Single With Twins]

I would say more like 65-66mph, just my 2 cents.
Good luck

How much more hp to get in mid to high 70's?

[88Fountain]

My 1988 29' ran 72 GPS stock with 454mag/365's and bravo's.

A friend of mine bought one of them new in 89. It had 420's and trs's. Full of fuel it ran 73-74. Light on fuel, 2 people I've seen 75-76. The engines were stone stock with the old style cast iron exhaust manifolds.

I have an 88 33'. You should be in the mid to upper 70's with about 450HP. I run upper 80's with about 650HP w/trs. I did have smaller engines before which ran in the mid 70's. You do need to have a dry, strong, staight, well kept hull if you want to run fast.
