TOO HEAVY? NEW 4 STROKES?

[Jason Stanfill]

LOOKING TO BUY A NEW ALLISON XB21 2+2 WAS WANTING TO KNOW HOW THEY HANDELED THE NEW 4 STROKE MOTORS AS FAR AS THE ADDED WEIGHT.

Good article.. I have a few questions. What WOT are they getting out of the 250R, 300R, on the 21's? What jackplates are they using, anyone running with power poles?

I see Glenn every couple of weeks. I'll ask when I see him. Otherwise Lee Sanderson, mentioned in the article, is on some of the FB Allison groups if you want to check with him.

Tim Powel (sp?) at fastbass marine posts here and on SnF. He has prop comparison videos using V8s on the big Ally’s

Check out my Fastbass Marine TV youtube page. You will own a V8 Allison after watching. LOL No issues with a V8 on the 21' boats. I have tested with power poles on my 21' XB21 300R. Video's on the youtube page.

It’s such a shame that Mercury abandoned the lightweight performance market.
More power in their V6 line would be a step in the right direction. The 200 ROS seemed to be the start but since it was dropped I doubt we will see anything.
I have a 200 EFI with the oil injection and rev deleted. Next is to cut the heads injector service and a Brucato ACU. I feel that’s the best route for me unless I can score a 225 pro max powerhead.
