Engine size on a honwave T40

[fishing4pike1988]

hI Guys,

just bought a honda Honwave t40.
ive been offered a 9.9HP outboard.
is this too small?
mainly bringing it on lakes but may go a mile or two out to sea.

any advice would be greatly appriciated.
It would be max 4 people on it but mainly two.

Thanks

Hi & welcome.
Personally I think you'd be under powered especially off the coast (fully loaded) but fine on the lakes. It's really surprising how an extra few hp can make a difference. I have a Honwave 3.5 AE and run a Tohatsu 20 4 stroke and it can get 5 of us on the plane but it's a heavy lump to carry about. I also have a Mercury 15 2 stroke, much easier to carry about but doesn't have the power for the sea (strictly my opinion) but is fine inland. With a 2.5 on the back it goes surprisingly well with two kids in it.

The T40 is big, solid and heavy. Its an excellent boat but the minimum I would want is a 20hp. I used an old school 20hp 2 stroke on mine and it planed even with 4 big adults on board.

I'm not looking for speed, just looking to cruise, should I just go for a 15/20 hp so?

Hi

How many will be on board, this will be your decider

From my experience with a 15hp on a T35 I would agree with the comments above. These alloy floor Honwave models are great boats but heavy and do not perform as well as a smaller/lighter SIB for any given outboard size.

To have reliable performance 4 up (assuming adults) on the plane you will need a 20hp really.

What do you mean by "cruise" though? Most of us would mean a comfortable speed the boat will easily maintain once on the plane... perhaps 15kts. The problem you may have with a smaller (than 20) outboard is that it may be capable of maintaining this cruise once it gets on the plane but you may find a 20 is needed to easily push it over the "hump" onto the plane 4 up.

When 2 up a 15hp should be OK but a 9.9 may be too small.

Hi al

If your gonna have a 20hp 2 smoke you may aswell go for a 25hp it's the same weight and the extra would be a noticeable improvement on a 20hp.Not that different in fuel either.
