Tohatsu TLDI engine


What are the real advantages of Tohatsu TLDI (direct injection) 2-stroke engine against normal Tohatsu 2-stroke engine?

And agianst 4-stroke engines (made by other manufcturers)?
Price is more or less the same.

Here in Portugal a 50hp Tohatsu engine is almost 40% cheaper than the TLDI 50hp engine.

is basically the Merc Optimax system by another name. (IIRC). So, digital fuel injection, lower fuel consumption (upto 40%, less emissions, more too go wrong!, etc etc.) I would think it would be lighter than the equivalent 4 stroke and probably give similar fuel consumption figures. That being said a 50hp conventional 2 stroke is not going to be that thirsty - The joy of things like Optimax are when you get too the larger hp ranges (150hp+) where fuel consumption is a real issue!

I run a 150 Opti and its great. No experience of the Tohatsu though.

Check out the article from Andy Clarke (Rib internationals outboard guru)
