200Hp on a 5.6m Boat???

[DaiwaFreak]

Hi guys, I have a 5.6 plate alloy boat which currently has an old 115hp yamaha 2 stroke. The trim recently died and we have decided to upgrade. We are looking at a used 200Hp Yamaha HDPI. Just wondering what you guys think. Is it too big??? and is it too much for a 5.6m boat???

Cheers,

Your hull should have a plate which states maximum horsepower and max motor weight allowed for the hull, you need to stick to that.

Can't seem to find an ID plate on the boat.

Id go to a few different Boat websites such as Allycraft, Stacer and Quintrex etc and see what the closest length and style boat is to yours and have a look a the Max horsepower engine for them, and use that as a rough guide if you cant find an ID plate on your boat. I'm just guessing here but a 200 sounds like way to much for any 5.6mt boat. I'm pretty sure you will find 125 - 150 is about the Max for your size boat.

What sort of hull do you currently have?

[DaiwaFreak]

Its a 5.6m Custom Plate Alloy. It was built by a WA company in 1994. Also, when the boat was purchased, the owner said that he was planning to fit a 175 on the boat.

do you have any more info on the boat brand/model? Like Emo says, you will need to comply with the build specs

Any reason you want the bigger motor or is it just that it is available. I suspect that with the 115 you are rarely ever at WOT on the water unless it is an exceptionally good day. A bigger motor isn't gonna help you push into the waves any harder coming home from a long day in the deep.

Just as a matter of interest the HPDI weighs 216kg. The current 115hp 2 stroke comes in at 163kg.

The only reason why I am considering this engine is because there is one for a good price and we are desperate to get the boat back on the water.
