Read some great reviews of the tldi in general - looking at the 2 engines there is quite a difference in weight - one is a 3 cylinder - the other is a 4. Normally I would say go for the lightest engine but there is quite a power difference. If you's asked about a 70 or a 90 it would have been easy!!!

It is quite interesting to see that the technology used is licenced from Orbital in Australia - the same people who developed Optimax for Mercury. i wonder if it's a pact between them that makes Mercury use them on big engines and Tohatsu on smaller ones???

Matt, I have a 6.1 Tohatsu but with a 150 opti on it. I goes very well (53mph on gps) but can be a bit of a handfull on empty tanks as it does tend to fly a lot and as its not particularly beamy, the landings can be quite interesting. It is built well, but I would definitely go for 115 instead of a 90. With full tanks (160 ltr) and 4 people, you will be happy you went for the extra power, even at the expense of a little more engine weight.

From what I've heard that is true. Originally Tohatsu / Nissan had the license to manufacture up to 90hp, while Mercury / Mariner could produce 90hp upwards. Although this has obviously changed with the new Tohatsu 115.

Matt, I have a 6.1 Tohatsu with a 115 E-tec. I get 50 mph with 4 up and it handles well, probably because the engine is not too heavy. I was told by one of the Tohatsu dealers to keep the engine weight under 170Kg which the 115 E-tec is, just!

Matt

Just noticed that you're in Portishead. Walton Marine (Harbour Road Industrial Estate) currently have a couple of 115hp Optimax's on offer (mid-5k). Would think this is probably cheaper than the Tohatsu, better resale and easier for you to get serviced?
