Voyager 248 Speed Question / 300hp

[Johnyrude200]

Hello All,

I'm currently rehabbing my 4th Grady - newly acquired earlier this year 1996 Yoyager 248.

I'm putting a 300hp on it - was wondering what types of max speed people have seen with this set up. Going to start with a standard 17P prop and see where the tach goes and adjust from there.

Boat is rated for 350hp - but I don't need that much I generally only cruise with my boats and very little time at WOT. But interested to see what to expect with this hull/model.

Thank you!

I have the same setup with a 250 Honda. WOT is 43mph depending on seas. You would probably hit 46 if I had to guess.

Thats interesting to hear thank you.
I have an older 1980’s 22 seafarer that I switched from an old carbureted 225hp over to a fuel injected 300, and its like night and day in terms of performance - propped the right way I can hit 50+ MPH which frankly is too fast for that hull.

45-50 with one of these boats is awfully fast and sort of not worth it unless its very calm waters, otherwise everything in the cuddy gets the hell beat out of it!

We had a bare bones 99 248. With a 225 ox66, it would hit 46 mph with a cupped 17m prop. With a 300, you should be able to hit 45-50 depending on options, engine, and overall set up.

Hey FA, thanks for the feedback! The motor Im installing is an ETEC 300 (Im a mechanic), and hearing your feedback as a fellow 2-stroke operator.

Those OS66 yamahas were the best motor they ever made snd thats coming from an OMC mechanic!

On a side note the 248 is the same boat as the 258 Journey introduced in 2005 and hasnt been given the credit it is long overdue for!
