Mariner / mercury 3.3 hp 2 stroke

Iam interested in one of these . Its the same as the 2.2 ,which looks very similar or the same as the suzuki 2.2. Finding info on 2 strokes isn't so easy now they are discontinued .
Only difference i can see is that it revs higher and costs about £150 more .

Why it costs so much more than the almost identical 2.2 i can't understand .

What iam thinkng is that because it produces the extra power by simply revving higher is it really any better ,
does anyone know if it actually turns a bigger prop or makes noticably more power at lower rpm.

I think the 3.3 has fwd and neutral and the 2.2 is direct drive. The 3.3 may have a few other features aswell, but I can't remember.

They're rebadged tohatsu's, the 3.3 is the same as the tohatsu 3.5, if you could find one it would probably be cheaper than a merc or mariner. Don't know about how the engines are tuned though.

Cheers Sam
Tohatsu still have all the 2 stroke on their site . The 5 hp also looks like a good bet at only 5 kg more than the 3.5 .
Iam off to price one up if I can find one

Ian check out HERE they have a selection of 2 stroke Tohats at resonable price.

They have about the best price around £385 for a Tohatsu 3.5 . Same as merc etc exept its called a 3.5 because the power is measured at the prop instead of the power head.
Also called Bill Highamas they advertised "please call as price is too hot to list" yes it was but should have read too "high to list" They said not many 2 strokes left , I said is that why our are inflating the price ? they said yes they are selling at a premium . Robbin Ba***

Plenty of time , I think Ill look for a second hand one

Hola Ian

Don't go for a Mariner/Mercury/Nissan 3.5, all are disguissed Tohatsu's. Get yorself a nice Toh 5.0, it's the same as the 4.0, but with bigger jets, more power. If you are going to invest on a new engine, then invest well, the power difference it's worth it. Tohatsu is still producing 2 stroke engines.

It's better to have more and don't need it than to have less and need it.

As said above the 3.5 has fwd / neutral gears - so safer to start.

The difference in power is due to a restrictor between the carb and the crankcase. Take the carb off, remove the restrictor - simply a round plate with a slot in it, put the carb back, job done.

At least this was what we did with a mates 2.2 merc to turn it into a 3.3 back in about 1988!

I agree with your logic but eveytime I go bigger the price doubles and the wieght increases . Smallest and lightest was the reason , so it is easy to lift inside the consul and onto the transom

Thats confirmed something i was wondering about Duncan thanks for that . a derestricted 2.2 sounds like a good bet to me , I don't need gears

Good price and quick delivery, can I convert this to a 3.3hp?

Probably, Pacer Marine are mariner dealers and have been around a long time, might be worth asking them to do it before the despatch it.

They also have the 3.3 for sale at a pretty good price , I would expect they would just want to sell you one of them .

Looks like the gearbox ratio's are different, 2.5 hp will have to do. Sure it will be quicker than the paddles I have used for any unexpected failures.
