Engine comparisons

I am narrowing on the size of rib for my use and now starting to look at where the money is - the engine!

Many users of this forum must have been through the same process of comparing engines. I am looking 90-115hp. I searched the forum and can't find reference to simple spread sheet giving manufacturer/output/weight/claimed consumption/ et cetra

Do I need to look further or should I start doing my own? Any help welcomed.

I can tell you usage data on the new Suzuki DF90 but nothing else.

I'm not aware of a comparison chart

Fuel consumption will be pretty much the same no matter what - if you are using say 75hp that is the fuel you will be using.

You will just have to look at the different websites - they have all the spec there. Personally I prefer 2 strokes - an Etec or an Optimax. Weight is the most important factor - all the modern engines are pretty good!!!

I have made a start at the comparison chart for engines 90-115hp?

I have tried a start at the comparison of engines between 90-115hp. Suggestion for other important fields welcome and I will try to add them.

Please find attached

Presumably, you're going to put Suzuki on there?

There may well be folks on here with fuel consumption opinion but you will need to be cautious with it. I suspect, like car fuel consumption, it will be notoriously optimistic or pessimisstic.

How about price?

There are some other factors that you might want to consider, but they're things you can't easily measure with numbers:

2 stroke v 4 stroke - very emotive on here.
Noise quality as opposed to quantity.
Proximity of service, support and parts.
Reputation
Cowl colour - does it 'work' with my boat

Just added Suzuki DF90 and 115, can't seem to get prices on the web, they all ask for you to call. Any suggestions for a good source of price data. p.s. I have some RRP prices for Honda and Suzuki.

How about service costs? it it a major factor, i.e. big differences

Depends where you take it...we take our boat/engine back to the boat manufacturer on the basis that whatever is wrong/goes wrong only comes back to the one company. Avoids all that tedious finger pointing and they give excellent service, although they're probably not cheap by comparison with others.

Bit of a mine field unless you ensure commonality...I suspect the only vallid comparison is if you quote the manufacturers agent costs.

Other nice option : Tohatsu 90 & 115

2 Strokes: If available
http://www.tohatsu.co.jp/en/boat/products/m90sp.html 3 cylinder - 135 Kg
http://www.tohatsu.co.jp/en/boat/products/m115sp.html 4 cylinder - 164 Kg

TLDI :
http://www.tohatsu.co.jp/en/boat/products/md90sp.html 3 cylinder -143 Kg
http://www.tohatsu.co.jp/en/boat/products/md115sp.html 4 cylinder -178 Kg

For a 5 + Rib any 90 will be perfect.

Happy Ribbing
