Advice needed - Tohatsu 90hp 2 Stroke

Looking for some opinions on a Tohatsu 90hp 2 stroke engine, on a 5m Humber Assault we are considering purchasing.

I've had no previous experience with 2 strokes, so really need some help deciding.
It was bought new in 2004, and has been used fairly lightly since.

Is it a decent engine? Should I wait for a 4 stroke to come along, as we first anticipated?
Or is that just silly? :P

Help!

Toahtsus are a little more agricultural than most other outboards, that's not neccasarily a bad thing. the engineering tolerances in manufacturing are not as close as other makes but that means thay can take a bit of abuse!

My experience of the is that they are OK but I wouldn't replace a yamaha with one

They're very basic (uncomplicated), which can be a good thing.

Not sure what your facination is with 4-strokes. Roll up your sleeves and join the 2-stroke revolution. Yes I know they smoke on idle, yes it's a pain to mix fuel/oil (unless it's oil injection), and you they'll hear you before they see you... but a 2-stroke (if properly maintained) is about as good as it gets.

First things first. A Yamaha 90hp, 3 cylinder, 2-stroke is the F1 of 2-strokes in the top-end of the torque/weight ratio. Tohatsu's seem to get a good name from commercial fisherman for their no-nonsense operation and they're 'built like a sh*t brickhouse' so no need to worry about bits 'dropping off'.

Regular maintenance is key here. Low hours can be as problematic as something that's been thrashed. If as suggested it's 2004, I'd be looking at a mint engine. I bought a 2006 Tohatsu 60hp and can recommend. Matched to a 5m Assault is a perfect match, as long as it's in decent condition too.

2 strokes I love um. Well maintained they are reliable, light and quick. However, they do smoke a bit and are perhaps a little thirsty but overall it terms of cost of ownership, ease of use and simplicity to service etc they can't be beaten, in my opinion!

A full set of service parts for my 60 merc costs 70 from Keyparts and I am guessing that for the Tohatsu 90 it wouldn't be much more.

If its in mint condition and runs well, I don't think you would have any concerns, I guess you could look at the gearbox oil and check the compression on all 3 pots.

Since 2002 I have owned 3 tohatsu's, 9.8hp, 50hp and my current 70hp. None of them have ever let me down once. They are indeed "old school" basic outboards which makes them very nice for DIY servicing.

I luv the sound ov em screamin along.

Tohatsu 2 stroke.

I replaced a Mariner 4 stroke 90 HP with a Tohatsu 90 TLDI on a 5.6m Avon Adventure.

It actually starts and runs reliably which the Mariner never did, and the power to weight advantage has transformed the boat.

They don't have much "badge image" but I would not even begin to think of going back to what I had before. Buy one, you won't be disappointed.

Hi Lewis,

They are a good engine, I have one on my Driver 560. If you dont go ahead and get the engine would you send me the link to it or location as I am after another 2004 90hp tohatsu myself
