decided on boat but which outboard?

Hi all,

New to this forum, attempted to get going a few weeks ago but unable to. To be brief - i have a thousand questions to ask - :-

i have decided today to buy my very first boat and have a problem deciding on make of 2 stroke outboard.

To be fair to all i have ordered a Zodiac Futura 4.10 which is not strictly a RIB so before i go any further i hope this is the right forum to be asking advice on!

My first 'problem' is make of outboard. I have been told that Yamaha are very very good but have found a 2004 second hand 2 stroke Tohatsu outboard for a good price. It is as new.
My question is, will i be missing out on any benefits, if any, by not buying a 'better' outboard of same power and stroke, eg better grunt, auto mixing etc.

I have done my research but have no experience.

I hope you RIB people will help and/or direct me to the right place.

thanks

Tim

Tim. I have always had mariner 2 stroke engines and have never had a problem. I am no expert on outboards but have driven boats with the same size engine but 4 stroke and do not have as much torque but then again they are more economical. Someone may care to correct me.

What sort of size are you looking for? Yamaha are good engines, as are Mercury/Mariner (same engine 10% more if you buy Mercury??!!?). Johnson/Evinrude (same engines) are OK but since being taken over by Bombardier I don't think are as good as they used to be. Tohatsu tend to be old technology 2 strokes, which isn't a bad thing it just means it may not be quite as refined as say a Mariner or Yamaha.

cheer guys for quick reply!

The boat is only between 69kg and 102kg depending on floor type.

I only want/need a maximum 30hp.

This Tohatsu is 25hp, 2 stroke, 2 cylinder, non oil mixer, 2004, long shaft.


How crude are they and does this mean they are not so powerful, quiet nor fruigal on the juice?

Wy go for a long shaft in a boat that does not have much of a freeboard. May I suggest a short leg.

You won't find many engines of that size which are oil injection without probably going over the boats max engine weight limit.

The Tohatsu will be just as powerfull as a Mariner of the same size it will just tend to make a bit more noise (due to there basic cowling designs and carb intake designs) and possibly use a bit more fuel (but I doubt it would be noticeable). From the Tohatsus that have come into work they do tend to be very reliable and pretty bomb proof they just look a bit outdated under the cowling, and the cowling design is an old looking type. If its the right price IMHO i would go for it.

Make sure you don't need a standard shaft length on the boat. I can't rember how high the transom is on them.

I have heard they are reliable.

I guess then that 25 hp is 25 hp whatever the make. Zodiac recommend a long shaft for the 4.2 m Futura.

Ok, so Tohatsu is a little dated, i understand what you are saying. If i should opt for this make then, do you have any comments on whether i should opt for the 30HP outboard and......

.....will i notice a difference in performance between 25 and 30 hp?

Tue, Simon,

Ive just noted your deatails and see that you both have powerful outboards and big boats! They look a bit beyond me at the moment, in terms of size, cost, power, storage etc.

This game is all new to me.

I also note Tue, that you are based 30 odd miles from my location - Plymouth.

I doubt if you went up to a 30hp 2 cylinder you would notice much difference. Not sure if they do a 3 cylinder (I know Mariner do), in which case you may notice a little difference as you will get a little more initial pull due to the extra cylinder, plus Mariner do an oil injected version (so I would imagine Tohatsu do a similar one). Though the 3 cylinder engine is a bit heavier so would probably not make it worth while

i get what you're saying, thanks.

I want, at this stage to keep everything manageable and light but still want some fun with pottering, exploring and pulling doughnuts whilst i get the hang of this boat malarky and start learning.

The 3 cylinder 30 HP 4 strokes jump up to 90kg which is too big at this stage.

Went to the boat races at Plymouth recently, had a look round the manufacturers - was amazed at the physical size of the Honda 300HP outboards.

They were gorgeous.


Simon: the term 'freeboard ' means nowt to me! but i can guess it has something to do with the transom.
