There are a few in my harbor with a 225 John deere 6068. they are lobsterboats and WOT is about 21/22 mph. They cruise all day at 18mph. Depending on the gear. 2 to 1 has ... I'm thinking 24 x 24 and the 3 to 1 has 28 x 26

I think a 20 inch wheel is pushing it on a 25 BHM


OOOOOOOPS

I stand corrected.. I have no idea how 25 got past me..The wheels are for a 32bhm.

I would need to guess a 25 would need more wheel than the 32.

I would need more info to guess at the right wheel for the 25 since I never even seen one. I know they were the original biggest little boats in the bay.

Lobster,

Are you sure you are not posting about a 28 BHM?

I agree with Traditions, 20" wheel reg on a 25 BHM and how the heck would ya fit a 6068 Deere in a 25 BHM ?

Here's an 83 25 BHM I looked over two + years back. I think I measured the wheel @ 20"

Had a 262 Chevy straight 6 and a Borg Warner velvet drive in.
Not a lot of room. :confused:

Bingo Lobster, you beat me to the post !:D

there musta been a dozen 32BHMs go through my harbor over the years.. I think I get a automatic picture of a 32bhm as soon as I see BHM. Maybe the header of the thread triggered that and the 25' in the post didn't even register:confused::confused::confused: I would guess a over sqare wheel would be needed. 20 x 26 ??? Who knows what the gear is?

Can you imagine a 6068 JD in the front trunk cabin of a 25 footer ?? :eek:

This was the first boat in my quest for a DE to bring to Alaska. This one had a 210 cummins in it and the owner told me it cruised about 12 and ran wide open at 16-18 knots. Seemed kinda slow to me and he already had a buyer when i called on it.
