**racervboat** · 10-11-2017, 04:17 PM

Well I think it should be in the tech section? since its a work in progress I guess. So we were out couple weeks ago and he hit the gps at 87 mph with a mild 175 hp 1980 ish v-6 omc 28 chopper- damn could not believe that so we said lets start a new thread for the viper and get it into the 90s should not be a problem at all.Have some vids to load but will take a few days to load and post. Hope you're reading this gary [oldboatman] lol yous got one hahaha.

So we tried to go out on sunday but it rained so bad the past week the dock was 3/4 under water and 10 ft just to get to it and mad there was crap floating like TREES so no go lets save the haul lower unit and prop for next week.So got to the shop to watch nascar [78 won again] so bench racing and beer all good.

just a quick reminder about using a tramsom lifting prop [eg 4 blade]. you'll lose your steering with the hull totally out of the water. almost lost a vamp using a turbo 4 blade at 75 mph

was running a 3 blade chopper going to put the 30 cleaver back on but have to re hub it as it has a 13 spline in it now or get a different prop? p/s were not new to this game. Just to say, thanks for the input.

Wow...90+ in a 15 footer!? Please accept my most sincere compliments in saying that you guys got balls bigger than church bells! I wish I had those...would love to see footage of one of those runs! That's some next level stuff for sure!

Running really solid now that the battery is in the bow. 2.5 inches set back and 1.5" above the pad and dead level on the trim and feels great. Gonna bump the trim one or two and see

My best speeds and handling were with 24~28 ET or Yammie drags about 1 1/4 up.

**rjdubiel** · 10-11-2017, 06:42 PM

Those props are out of my price range! I bet there could be a major increase had with some lower unit work. She ain't pretty.

**racervboat** · 10-11-2017, 07:31 PM
