Engine sizes

Can anyone advise on the minimum size of engine that would provide adequate performance on a 5m Chinook please? High speed isnt a big requirement as the boat will be used on rivers and estuaries initially.

Joe

Haven't fitted the aux bracket yet


Course, it all depends on what you think is adequate (actress, bishop etc...)

I was looking at my transom working out the best way to fit the Aux . It looks like with the main engine tilted right up the aux may clamp next to it . I couldn't run like that but lifting it on and off is the intention anyway . Its only the steering ram that is in the way of the clamps when the main motor is lowered .

Think Iam going to buy a new motor now , 200 plus for 10 yr old motor is too much IMO .
It has to be iether 3.5 tohatsu or 2.5 suzuki 4 stroke both same wieght and price , would prefer the suzuki but unsure if it will have as much go as the tohatsu . Iam thinking 4 stroke torque against the 2 stroke revs for slow speed use ?

If you want to be able to get on the plane with 3-4 up I think you'd need a 50HP mimimum though you may find a 60 to be more ecconomical as it wouldn't be working quite so hard.

Thanks for that. The DT60 is no more and I have been offered a low hrs (20) 30hp engine complete with all the ancillary equipment. I am aware that it is half the power and cant expect the same performance as the 60 but wondered if it would be just too underpowered for this boat as to make the purchase not worthwhile?

Bigi,

As Marky says, it might struggle 4 up, BUT, with the correct prop you might be OK, if a little lethargic with the top speed.

Many years ago I drove a 5.4m Searider which was Ex twin 30. One engine was away for a service or something and the boat planed (just!) on the single 30 with (I think) 4 or 5 aboard.

What's this 30 Hp engine? If it's a Suz I think I know someone with a spare 12" prop if it labours....

It might be usable in sheltered water, but I reckon it would be a rather unsatisfactory experience.

I'd look for at least a 50 or 60. It would be well worth it in the long run.

Have fun!

John

Thanks for the valued advice guys, I think I will look at something a little larger. Cheers.

Sorry Joe
I didn't mean to hijack your thread , somehow I thought you were asking what size minimum for an aux motor doh

There seems to be a reasonable choice of used motors about in the size you need ,or so it seems while I have been looking for small one anyway .

Good luck
