Engine choices

[fjarvis]

I'm going to buy a new BRIG Falcon 400S RIB. It's a 4m RIB, rated to take 112Kg engine Max 50HP. The engines I'm looking at are as follows:-

1. Yamaha 40HP 4stroke with PT&T - Weighs 90Kg
2. Suzuki DF40 4stroke with PT&T - Weighs 107Kg
3. Tohatsu 40 TLDI 2Stroke DI Electric Start with PT&T - Weighs 96Kg

1 and 2 are probably the easiest options as the dealer which I'm buying the RIB from can supply and fit them, if I go for the Tohatsu I'd have to get it elsewhere and have it rigged by a marine engineer seperately.

The Suzuki seems to me the best option as although a bit heavier it's a downrated DF50 and it's also £300 cheaper. Is that a reasonable decision to make or is there anything else that I should be looking at? I also considered the 40HP Evinrude E-Tec, but it's quite heavy at 112Kg ish.

Cheers,

Ive got the Tohatsu 40 as weighing 59kg and the 50 as 69kg.

If its a small boat its going on thats a huge weight saving over a fourstroke, may handle a lot better

Get the Tohatsu 40, it will then go S*** of the shovel !

The TLDi model is a lot heavier - 95kgs as it's the same block as the 50hp TLDi.

The conventional 2 strokes are a much better bet if you want to drive like a maniac.


I think in this case I would go for the Yammy - or a normal Tohatsu 2 stroke - some great deals to be had I think.

Thanks for the suggestions folks. Will the extra 17Kg for the Suzuki really make that much of a difference? £300 is a big saving! Plus as it's from the same block as the 50 I figured that was a good thing. I did want to go 4 stroke or 2 stroke direct injection. Tohatsus are also more difficult to get serviced up here there are not too many dealers in Scotland.

Suzukis are lovely engines - 17kgs not a massive difference I suppose. If it's the same weight as the 50hp why not go for that? Or is it a lot more?

It MAY even be possible to up the 40hp to 50hp at a later stage - on some modern engines it can be as simple as a chip or restrictor or similar.

To be honest what you save in fuel over an older 2 stroke will prob make more than 17gkgs difference - you can carry less fuel......

17 kgs is less than a jerry can of fuel and that doesn't last long in mine!

Good point. Just been offered a new 40HP Evinrude E-Tec (ex-demo, but never been run) cheaper than the Suzuki and it's a few kilos lighter too, I think I'll go for that.

Thanks for the opinions folks!

At the end of the day ALL the engines are pretty good - it all boils down to the best deal at the time!!!

Why a 40?

I'd stick a 50 on there if it's rated for it-specially with 40s and 50s weight being so similar.
