Is 120hp too small for 21ft center console

[Destroyer]

Anything larger than 80HP WILL get your boat up on plane, so yes, like Skunkboat said, it will push your boat. NO, it will not push it fast, but it will get you on plane. My guess will be in the low 30's, depending on load, wind, current, tide and prop.

Would I put a 120 on my boat? NO, not for a second. (Well, that's not quite true... if you look at my signature you'll see that I have a 120 Force on my Wellcraft Airslot. It's a good engine, but remember that my Airslot is only 16.5 foot long). Would I hang one on my V21? No, I would consider it way too underpowered. For me, the least I would use is a 150HP. (With the exception of the Suzuki 140 that thinks it's a 150)

Pic is of the 120 Force pushing my Airslot.

I ended up getting a deal on 2 Merc 125s ones a 98 saltwater and ones a 2000 offshore. They both work but price was rightook the offshore apart last night and hope to be fishing by Sunday. Also what's the difference?the offshore and saltwater look identical

I answered YES to the question "Is it too small...?"


Anybody that wanted to put holes in a motor to make it louder is not going to be happy with a 125.

Your right. Fired it up tonight.....sounds like a Honda Civic. Not the bada$$ black max sound. Oh well kids are dieing to go crabbing. I'm sure in gonna need a different prop any suggestions or should I post a new thread?

Hmmm....?? He asked "Do you think with hydrofoils and a good prop this motor will work on my boat?" He was talking about getting the 120 Force. I thought that's what you were answering "yes" to Skunk.

LOL either way, I think we're both in agreement that a 120 is just not going to cut it long term for a V21. Yes, it will get you up on plane. But the extra cost in gas and wear and tear on the engine to always be running at full bore is going to seriously shorten the life of the engine. (IMHO)

It will or should get your family on the water but you probably won't be happy with the performance but than again maybe you wil

It actually did better then I thought.top speed is the only major difference I noticed so gas. Bit it looks like I ha r a mystery noise in my new motor
