Valiant advice

Hi guys,

We have a DR 750 from 2004. A mate here in Spain is looking at buying one from 1996 but has hit a snag. The paperwork on that boat says it's max rated power is 200hp. Ours says 300hp.

My question is, is the paperwork correct or possibly a typo? Can't find out yet what the makers plate says as the boat is nowhere close to the seller.

Appreciate your thoughts.

Needs to check the plate.
Valiant's website shows one 750 currently offered & whilst it gives 300hp max they recommend 225hp.

Hi Paintman and thanks for the reply. We now have more complete paperwork and all of the stats differ from our 04 version. Less total payload as well. So it seems the 200 is not a typo.

Changing the question slightly does anyone have an opinion as to what the minimum power for this boat would be? I know that's a massive variable depending on load but what would the minimum power be in order to get her on the plane with say 6 aboard plus dive kit? Say 800kg. I ask because I have been offered a Honda BF135 at a reasonably good price. Maybe we could recover something from this?

How does yours perform with the 150?

Days gone by

We don't have this engine anymore but it seemed to work ok. There's no doubt the Honda 225 we currently have is quicker but the old 2 stroke 150 was ok. You think the 135 Honda would be it's equal?

Bare minimum to get a boat on the plane is about 50hp/ton but that really is a minimum. So your probably around 3 tons fully loaded....a bit borderlline ?

Your 150 two-stroke was probably well up on torque compared to the 135 Honda as well and that's going to make a difference.

I'd look for another 50 -100% on top of that.
