What speed boats can safely handle a 3.0l+ motor?

**mxz** · 05-09-2013, 03:51 PM

Since Allison is against putting a 3.0l or bigger motor on a Grandsport I am curious what makes of speed boats can safely handle a 3.0l motor or bigger such as a 225Etec HO or a 225ProXS? Talking about full interior boats, not race boats.

My 17'9'' V-King handles the 3.0 with no problem.

how much set back do you run on your vking i have a yt and i'm wanting to put a 3.0 225 carbed motor on

I have a land and sea jack which has 5'' of set back. I also run all the weight in the stern. Tail heavy at slow speeds, but gets up and flies good. My sig pic is a shot of it in the mid 80's. Very little trim.

thanks i run a 2.4 on mine it has an opti cowl on it so it looks like a 3.0 with 10'' of set back got 85 out of it with me and wife in it love the boat

My Riot loves my 15inch 300 ProMax. I know it`s a little high but thats only through exceleration then i bump down for top end.

It's not they can't handle the power, it's just that some of them handle better without a heavy motor on the back.

My Allison GS handles the 3.0L just fine.

Once you feel the torque of a "big" block it's hard to go back to a 2.5 motor. Not much difference in top end, but the low and middle is more impressive. I'm talking stock motors here, a modded 2,5 is a diff animal..

yeah i've got a 97 250 efi on a 25' dusky v berth ugly boat but great ride and that thing will jump up and i've gotten 44 mph out of it

SRV and V21 work very well with 3L+ motors. I would think that any of the 20+ ft boats would run well with the bigger motors.

I said "safely" I have been in a few Vkings and none of them felt very safe over 80mph...harrells I sent you a pm.

I thought real hard about buying a new pro xs for my V21 but with a wedding coming up went back with a new 2.5 power head.

I have a 3.0L 225 Sport XS on my 2010 STV Euro... no issues

**obrien** · 05-09-2013, 08:16 PM

I have a 3 liter 225 efi on the back of my stratos 200 vt ski. So far I have seen 83 mph with a 29 tempest plus on the limiter. I believe there is still one for sale here
