Re: Anyone know this 28?
 

NotRight,I'm seeing 80-81 gps in lake Ponchatrain.Chine walk can be an issue at times,gotta stay on top of it and turn "into" it rather aggressively to stop it.What I don't like is the "lean" to port after 70(prop tq)Thinking about a 1" shorty? My 548 is making 650 hp with efi. BOB

Re: Anyone know this 28?
 

Anyone know what kind of speeds I cant expect out of a 270 with the 502 efi in it? Just got it and have not had it in water.... Cant wait til summer.

Re: Anyone know this 28?
 

I had imco single ram hydraulic steering on my silencer. Seemed to help a lot with handeling issues at speed. 454 mag mpi and the boat ran about 66-67. needs k planes to handle a little better. The bennets are worthless. 70 is realistic for a 502 boat with a labbed prop. I ran a 24 merc 4 blade.

I had a 98 270 with a 454 mag, so 30 HP less than you are running. Ran about 61 0r 62, speedo showed higher, as they all do.

Re: Anyone know this 28?
 

In flat water mine seems to get a little squirely at around 67-69. I have an add on single ram HD steering.

This winter I replaced my 12x12 Insta Tabs with 12x16 Insta Tabs, I am also redoing the gimbal ring, which had quite a bit of play in it. It should be much better.

Speedos are the devils work!! They always lie:D

Bob, is that your boat in this months Hotboat? there is a write up on a poker run in New Orleans, one of the pics has a 280 Silencer in it.

Would that be the March issue? I noted there looked to be a 28 in the Powerboat issue last month at a poker run also.
