18hp or 15hp??

Hi all could do with some advice, I'm looking at getting a new outboard, I am looking at the 18hp tohatsu 41kg or yamaha 15hp 36kg, so is the extra 3hp worth the extra weight ??

Slate when I wanted to upgrade my Mercury 15 I looked very hard at a "hooky" new Tohatsu 18 2-stroke vs the Suzuki DF20 4-stroke that I ended up with.

Are you upgrading from a 9.8? I would have thought either a 15 or 18 would be a good power increase on a small RIB which must have a pretty efficient hull. What sort of speeds are you seeing now?

Assuming used I'd be tempted to go for the best condition you could find be it a 15 or 18.

I sold my 9.8 it wouldn't get two adults and a child on the plane so I'm going to buy new, It has to be 2 stroke because I lanch from the beach so weight is a factor, on my own in the boat with a 9.8 I'm getting 18 ish mph, with myself and nephew 15 ish, but with the three of us it wont plane

How does price stack up?

One reason why I found it hard to take the Suzuki 20hp 4-stroke vs Tohatsu 18 2-stroke comparison past an initial interest was the supplier of the Tohatsu wanted more than the local dealers did for the Suzuki. That was enough to reinforce the 4-stroke advantages for me.

I can get a 15 Hp yamaha for 2100 and the 18 Hp tohatsu 1900 just wondering if the extra 3hp is worth the extra weight

Extra 3hp is 20%!

I'd go for the Tohatsu 18... in fact had I been offered one at 1900 new I may have one now! I was being quoted something over/around 2400.

I honestly don't think you could go far wrong with one. They are easy to work on and have a great reputation for bulletproof build.... always hold their money second hand too.

The Suzuki 20 is only 44 kg and would be better fuel economy giving 50% extra power over your original engine also giving you some throttle redundancy.

Cheers
