90hp Tohatsu vs 90hp Yamaha

I have a A1 Condition Searider 5.4m without an engine. I also have a 2004 90hp Tohatsu with 77hrs on it. It is in the best condition. I have the engine sat on my Driver 560(speedboat). My Predicament - I am a huge fan of Yamahas. I currently have 2x 75hp Pro on my Atlantic 21, 1x 80hp on one 5.4m, 2x 40hp on my other 5.4m. Apart from the 80 with a stator problem they have been the most reliable and best performing engines.
Now do I sell my Driver and Tohatsu 90hp to then find a Yamaha 90hp of similar age?
Any thoughts would be most appreciated
Have a look at my website for pictures of the boats named above.

for longevity it has to be a yammie 2 stroke. the Tohatsu's are good enough engines but they are not made to the same tolerances or finishing as a Yammie.

I'd put either on my boat but i'd be prouder of the Yammie, if you know any experienced Zapcatters ask em what the first thing they do is with a Tohatsu, If I recall correctly it's take the engine apart and rub off all the moulding flashes, now that's the kinda thing I like a manufacturer to do.


Having said all that if I enjoyed the driver then I'd be keeping it and sticking the tohatsu on the Searider andlooking out for an old 90 for te driver

I love twins are your twin 40's contrarotating. We put twin tohatsu thirtys on a 4.7 which lives on a tug in Poole and boy did it look snazzy, the Rib not the Tug

The driver is an absolutly cracking speedboat. So much better than my Ring 18. Having said that, I dont think the 90 does it justice. It needs a 150. The reason we whack tohatsu 50's on the Zapcat is it is so light and powerful for a 50hp. We use them on our 4.7m Zodiac in the Marines so we can lift them with one man.
I am still massivly stuck what to do!
I am very chuffed with my twin setups, They are so handy for teaching and redundancy, its great. Unfortunatly the engines are not counter rotating yet. But I might get round to changing the setup.

It was too small for what I now need. Want something about 6.0m with a yamaha 4 stroke! Would have loved to have kept it but cant have 2 boats at the house.

Just happen to read an old magazine test comparing various 85-90 hp 2 stroke carb engines. In that test Yamaha 90 was slightly faster than the Tohatsu 90, but substantially more economical (both engine had standard props). One the pdf cant find the year the test was performed, but can be mid -90

I hope to have more practical experience of the Yam 90 in near future.....

sorry buddy I meant the guys racing them, they have to put Tohatsu's on for homologation purposes, although they do the job superbly. How many 50's have you whacked on yur zapcat?

I think the answers in your threads keep the Tohatsu stick it on the Searider and get an xr2 or old merc 150 for the driver when you can?

Re Hector he's a worry hes sold his Searider and he's talking about buying a Humber!

I was thinking the same thing. I have had a humber and they are a heap of S**t. (sorry for all those who have one). You cant even compare the two brands. I have been racing zapcats for years now. I have been through many engines, but they are very forgiving. I think you are right about the XR2 on the Driver.
:Still unsure about keeping the tohatsu though.
