15hp 4 stroke

Does anyone on here use this size engine on a sib.If so what sort of speed are you getting with a light and heavy load.Also is the engine noise quieter than a two stoke at tick over and through the rev range.

Hi anthony

I have a Zodiac 340 Fastroller Acti-v with a Honda 15hp FS. I have found it to be a great fast little boat. While also handling rouger weather and surf. 15hp is the maximum power for the boat and i find it to be plenty adequate, it has never failed to get on plane even fully loaded with 6 people and kit. I have managed to wakeboard and knee board of it which i find amazing ( i have not tried doing it with a heavy person i am 11 stone )

Speed: Lightly Loaded 1up 22kts

Lightly Loaded 2 up 19-20kts

I think a fs will be quieter but mine sounds loud at WOT

Not a SIB but I followed a dinghy back in the other day which I am sure had a 15hp Yamaha on the back and he was doing about 18 knots pacing him at a steady distance, and that was with an adult and 2 kids on board. I suppose it was about 3.5m long didn't have a tape measure handy.

Wished he would hurry up as it was bloody tipping down with rain but I thought overtaking him in a narrow channel might sink him and cause some whinging

I have an Avon 4 meter workboat with a 15 four stroke yamaha. I would estimate about 24 mph with 180 lb. load. It seems quite lively at any rate. I bought a set of lifters off ebay and the boat pops on plane very quickly. Only problem is the engine is on the heavy side when i use it as a kicker on my center console aluminum boat.

I have a Suzuki 15hp 4 stroke on a Quicksilver 3.1m - even 4 up it will hit about 20mph. It sips fuel - a 3 gallon tank lasts all day. Engine is very quiet at tickover but gets a bit noisy at WOT.

To be honest though I still think a Tohatsu 18hp 2 stroke would be a better bet - so light and much easier to lug around.
