hi question for all of you men and women in the know,, i have a 41 inch glass deep vee hull iam thinking on installing a HPI , 25 big block, i looked up the specs on it,, it hads 2.5 hp, think that would be enought?thanks mark

Believe It

IMO a 21 probably doesnt have the torque to get a 41" mono/deep v movin as good as it would with a 45.


then again if it was me i wouldnt put anything smaller then a .65/.67 in there.

My Feedback: (12)

Yup, it's definitely big for a .21 size engine. This size would easily handle a .45 and a .67 probably wouldn't be a stretch either. It would help to know which hull it is.

I'm runnin a k&b 91 in my 40" prather,soon to be completed,(waiting on my pilots license ),the name of this boat is ...........you guessed it.....overkill......[:-]

I'd drop a .67 in that deep vee. They are used in the 1/8th scale hydros which range from 40" to 53" long, so as Piper chuck said "it's not a stretch".

ill guess ill wait till i can find one i also have a dumas glass 31 inch deep vee the motor should be ok just air cooled.. iam also working on a jet stream i removed the 10 installed a aquacraft 15.. and removed the silly gear reduction. i also have two trazzas 2.5 one reg one and a R,might install one of those and be like a nitro v.well anyways it keeps me off the streets lol

I have a 41" vee hull with an ASP .46 and it is too sluggish for me (mid 30's). Hoping to refit it with a .67 to squeeze some more speed out of it. Therefore I reckon you will be well and truley under powered with your intended setup.
