And a gearcase if you want to last more then 10 minutes



get the torquemaster conversion for the yammajamma and go haul some a$$, no one said it would be cheap.

Never ridden in an Allison, have ya

Not an Allison that was underpowered, no. Have you?


I own one. Ask Ken.
A 20'3" Allison was 69 to 70 loaded and 74 in the winter with one person and tackle.
With 200 its an mid 80's boat, loaded.



The 21 is only going to run in the upper 70's with a 200 but I don't think the question was about the lightest boat, just a normal bass boat.

All of the companies who used to do programming have quit after the EPA sent them a letter.
Simon Motorsports quit advertising their upgrades and I think Hydrotec has also quit their upgrades.
I don't know about Nizpro since they are an Aussie company.

Pretty much the same thing happened in the diesel truck market. Dang EPA is a buzz kill

An under powered boat will absolutely get you by... but that one time you get caught up in a storm or some giant rollers you will be praying to the lord for those 50 extra horses. cheers

Or how about that annoying ramp when you’re loaded extra heavily? You have to pull the trailer up to keep the nose from ducking the roller but you don’t have the power to push yourself up all of the way. You have to do the boat ramp shuffle back and forth from boat to truck to get the darn thing loaded. mad

Save another few grand and get the big motor. As mentioned, most 21s NEED that extra umph. thumb

Yes the Allison is an anomaly for sure. They hold world speed records in nearly every horsepower class.

However for the purpose of this exercise I think the OP should steer clear of a 200 on a 21' boat.

On that boat it would be ok because it was built for speed.

tmd, keep in mind the OP was talking center-console boats, most of which are far heavier than an ally, and have a deeper V. No comparison. I'm sure Steez was commenting from that perspective, not the Ally that has nothing to do with this thread.


Where did he ask about a center console boat? I guess I missed that part on his original question.

He didn't ever say anything about a center console. But flippin doesn't like to respond when you point out he is wrong

He did not mention CC. I carried that over by mistake with switching back and forth between two threads. (The other involved a CC boat.) My earlier comments on this thread did NOT mention or assume CC, but the gist still stands - almost any bass boat is heavier than an Allison. Many of them are also deeper draft.

Hey Dub-dub, go shove it somewhere else. I don't avoid any thread. In fact, why don't you go compare how many I've helped to how many you've done the same for? I was busy on multiple threads, and carried the CC thing over on ONE comment on this thread by mistake. Jumping someone is the best you can do vs. actually solving a problem?
