re: What performance should I be getting out of a 35hp GTR gatoetail on an 1854 hull?

With the 25hp and those mods you should be seeing better rpms and speeds than that. The limiter is set at 4750 rpms so I don’t know why you are getting such low rpms. If that’s the stock prop your performance should be better than that. Are going WOT with about 1/2 to 1/3 of prop still in the water?

Its the stock prop. Thats at WOT and then later I typically back off a little once running. Its hard to see the prop, but there is somewhat of a rooster tail. I've found the best speed at two pushes down from trimmed all the way up.

I have seen it shoot up to and sustain 3,800 rpm at times with no change in throttle and its magical. Throws a higher rooster tail and speed goes up. I just can't replicate on my own at will so I think those occurrences are depth related.

Out of the water I squeeze her up to 4,200-4,300 rpm. Maybe I am governed down too much thus leaving those 400-500 rpms on the table? Idles around 1,100- 1,200 rpm.
Its a 22" transom including the hunt deck, which is what Gator Tail lists for similar sized boats on their site.

I'm wondering if its load distribution. So far its just been me with not much up towards the bow so maybe its squatting back too much unless on a flat where the bow gets pulled down. Could be a mod-v bow effect.

I'd have to talk to Delta to see if performance engine governors are turned down from the Vanguard factory setting before I mess with the governor.
