what is the biggest motor you can get away with on one of these boat. i have a 25 merc but it is to slow for my liking!

[Jack Mauger]

Max HP is 30 unless you pay to strengthen the transom.Look at the max weight of a 30hp as there maybe a 40 hp the same weight - the only problem is then getting insurance.

I had a 25hp merc sea pro on mine, it was stolen off the back a couple years ago,i replaced it with a 30hp yamaha and its a far better motor. with full casting decks batteries and gear, i can get about 48km/hour out of mine.

my was saying somthing about getting my motor upgraded to a 30. How is that possible and would it really make much off a diffrence?

[Kyle101]

I know that with some 2 strokes you can replace the carbiretor with a larger one and in turn the horse power will go up but i think if you do something like this the cowelling may not fit, not 100% sorry.

Possibly trade your current motor in for a 30hp 4 stroke (the extra money you spend you will make back in the long run on fuel)

Cheers Kyle

[sammy]

ok thanks mate, but would i notice more power if i upgrade to a 30

[Nugget]

Have you spoken to solas or similar about what a prop upgrade could benefit you with? They may have something that will pick up top end but possibly sacrificing lower range.

[Cheyne_jones]

What sort of speed do you actually get at the top end mate? I cant see another 5hp making a huge difference at all.

I have a 30hp Suzuki on my 425 Edgetracker, with 3 people and all the gear (batteries, leccy etc) we can do 23 knots top speed which is pretty respectable, if you are getting close to 20 knots I doubt you will gain alot. Maybe as suggested try find a new prop, or you can play with the trim, that made a huge difference to speed and handling for my boat.

I wouldn't go 4 stroke either if you want more speed, the extra weight will eat up all the hp gains very quickly.

In my 399 proline + 30hp blue-band merc i get 28knots with 2 people and gear (10km/hr slower with the hydrofoil but picks up heaps faster)

[Bobby Bass]

I would just staywith the 25hp if its a option, you wot get that much more out of it.

building up the transom and putting a big motor on is not a good idea. the transom isnt the only part of the boat that will cop a hammering
