I would say nothing to choose between them - both very good. There is very little difference in weight either. £500 will buy you over 500L of petrol. As to resale I don't think there will be that much in it as most older 2 strokes won't be on sale any longer.

The tldi system is very similar to the optimax so will be better on fuel but will prob be a lot more expensive?

Does the 90 tohatsu have a stainless impeller like the 50? That'd sell the tohatsu to me over the yam.

Codprawn - You have always sung the praise of the Tohatsu on this forum. Why is that? I'm not knocking them, just wonder how good they really are? Does anyone here have any experience of BIG hours with a Tohatsu?

Bit smaller than 90hp but...

Tohatsu, on small river cruiser, 2004. 400hrs Plus, (will check logbook). Going Strong! As new! (Fresh water use though!)

Tohatsu are excellent engines, well engineered, reliable, though their not as 'stylish' as other makes, such as merc.

I have owned three Tohatsoooooooos now. 9.8hp 2002 on the kids 3m sib it has been, and still is an excellent motor.

Next a 50hp 2005/6 which has never mised a beat, and the latest is the 70hp after trading in the 50 for which the dealer gave me a very good px price.

The 70 has not been in the drink yet and I only bought it coz the first two have been so good.

Be quick coz the prices have been rising over the last few weeks bcoz of the carbed model ban on 2 strokes at the end of the year!

I know a few people who run them on Zapcats and they seem very bullet proof even when racing. I wouldn't hesitate to buy one if I was in the market for that sized motor.

Oh and I also pay a lot of attention to what people on here have said abhout them in the past - see I DO listen.....

I suppose when the TLDi models have run up a few hours, that will tell whether they can maintain their reputation for reliability. Tohatsu is apparently massive in Japan, but always portrayed as a bit of a poor relation in the UK, which probably results in a bargain for the UK end user

Tohatsu are actually Nissan and are badged as such in some countries, so , given time, there's no reason why they shouldn't build a reputation every bit as good as Suzuki or Yamaha.

may be better than Zuki, but Yamahas are have a tighter tallarence, i've had about 10 or 15 of the yamaha 40-50hp, and about the same in Hotsus, the ports in the hotsu are smarter, the yamaha is better made.

Its the other way around, tohatsu are badged as Nissan in america. The small mariner/mercurys are rebadged tohatsu, with only minor differences. Tohatsu are also the biggest outboard manufacturer in the world. Their popularity is increasing in the UK.

Is it true, tohatsu still offer the warrenty on their engines even if they are raced on zapcats????

In my opinion Yamaha are the best quality outboards and hold their value best.

the hotsue has a bridge in the side tranfur ports, it splits the port , makes a better loop charge, the crank is weak. castings are ok.

the Yama well she don't have the bridge in the side tranfurs, crank is strong, vary nice castings, yamaha hard ware make nissan hard ware look like bubble gum.

Ahh that makes sense to me now .

I know if I had a 2 stroke I would have the most confidence in a Yam its more of a known quantity to me .
