Upgrading to a 21' boat. A couple I'm looking at have 200hp. What kind of general performance should I expect? I know most 21's have 225 or 250's. Just sold my 2000 zx185 with a 150 vmax. It would run 60 with full tournament load.
Thanks!

That would depend on what boat brand you are talking about and how heavy a "tournament load" is. I would say for most regular bass boats NO. 21ft with a 200
Why would you want a 21ft boat with only a 200 hp motor on it, unless you don't mind slower speeds, then it would be ok.

A 21 ft boat with a 200 hp motor on it would not be an upgrade in my opinion. It is a long underpowered boat unless it is a boat built for speed, but even then I would not do that.

It will run like a 85 Ford F-150 with clogged carbs.

Don’t be mad, I said it.

If you are shopping now, don’t settle for an underpowered boat. A 21ft with 200 hp is gonna be a slug.

Lot of 21 ft. center consoles and alum. boats with 200 HP., do just fine. Now the Bass Boat Fiber Glass series need that 250 HP to get the performance.

There can be quite a weight difference between various 21' hulls by themselves. Remember you're going to want bigger batteries, so even more weight there. The trolling motor on that 21' probably needs to be 36V, so that may mean a 4th battery in the boat (over and above bigger batteries), and the TM will weigh a bit more. Getting a hydraulic jackplate? It will have a larger fuel tank. When you fill that, well, there's MORE weight. How many people have you found who had bought a 21' boat who said "Ya know, I just put too much HP on that boat."

I like the 85 Ford reference; it's probably accurate. You better ride in the hull you're getting with a 200 & a load before you commit to that. Lots of room for bad decisions not easily fixed.

Never ridden in an Allison, have ya

you are looking at a terrible terrible hole shot and probably a 55mph boat with 2 people, full gas tanks, and full live wells. you will be disappointed with a 200hp in a 21 ft. glass boat. as mentioned above it will be a slug. good luck

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

I'd say 225 minimum. You can get plenty of hole shot by putting a 19 or 21 pitch prop on it but will not get the top end. A 24v Xi5 is plenty good on my 21 foot Triton even in the wind. Lithium batteries would be needed with a 200hp to save weight. I would not fill the gas tank over half way either and would not put Talons or power poles on it. My 21' Triton with a 225 Opti will run 74 if the lake is smooth enough so unless you don't care about the top speed I would hold out for at least a 225.

older 20' rangers were rated for 245 but most came with 200's. Mine runs bout 55 with a full tournament load. I really don't have a problem with that because after I get on plane I slow down to about 35.

Had a friend many moons ago with a XB2002 w/ 200 Promax. Ran mid 80's with ease. He swapped it out shortly after to a 260EFI and it would nudge 100 light and 90+ with 2 and gear.

I have a 21ft with a 200 black max its an old heavy Cajun Runs 57 with 3 adults. Once I get on plane I dial it back to 35, like stated above Im not there to race, just fish. Plus I save on gas that way. Theres a lot of pleasure boaters on Alan Henry and it sucks to take a big wake @ WOT. Really its a personnel preference

I KNOW THAT'S RIGHT !! LOL!!!
