Engine size

[timbo]

Hi,
I have just ordered my first inflatable its an aluminum floored 3.5mtr aqomar the company I am buying from are supplying a 6hp Johnson engine I will be using it on a large lagoon near where I live as a fun boat the waters are in general very calm but could anybody advise me if they think this size of engine would be big enough to carry two adults and two children at a reasonable speed and will it be able to tow a doughnut etc

No, it will not perform in a manner that you appear to want. What is the max. hp the boat is rated for?

[Nick Hearne]

15HP I would think would be the min. you want if you are going to use doughnut!

A 3.5 metre should take a 20HP but have a look on the transom for a manufactures plate which will tell you the max engine allowed ,20Hp should be enough for doughnut rides from a small inflatable, forget the 6Hp though thats not even enough to get you on the plane even without towing.
