Re: Engine programming

I would have been a little disappointed if I ordered a 250ho and got a 250. The ho is $2-3k more the 250. Hope you didn't pay for an ho.

Re: Engine programming

No. I back tracked to the order list. I said HO. He didn’t write it down. No leg to stand on. They set me up with the RX4 22” prop. I am 210 lbs, the wife, and two kiddos. Full 55 g cell. Can’t get 60 in it. Have the top, two talons and a mean trolling motor. Ice chest full. It will jump like hell outta the hole. Screams to 60 then kinda that’s it. My first pb. Sound right?

YYI. I have owned two ranger bass boats. I fish for whatever is biting. Got tired of only elbow room and the front always blowing with the wind. I have studied bay boats much. The PB is it.

Re: Engine programming

What rpm are you getting at WOT?

Re: Engine programming

It's more than just tuning differences between the 250 and 250 HO models. Reread my earlier post on the motors and Muskie's post.

 

The 250 HO also delivers its full horsepower at a higher rpm than the standard 250 - 5750 rpm vs.  5500.

Re: Engine programming

Well, just under 5300. I trim and tilt. Not much bow lift. Not trying to be greedy, but if it’s just me out doing my thing, I would expect more. It doesn’t fade off. It just hits 60 like a wall. Pitch should be well within the RPM range for wot. I’ll play with it more to see what I can get. I’m not shy of pulling it 10 hrs to have it hooked up to see if it’s been retarded.

Re: Engine programming

Try a 20" pitch RX4 and that should give the rpm a boost. You can also experiment with the engine mounting height as every little bit helps when looking for some more speed.

Re: Engine programming

Muskie, thanks for the details, I must have missed the port timing difference in the 3.4L's, in the training.
I expect that it will be quite a few years before I have any need to get inside a G2 engine.
