Info on 40hp
 

Im in the market for a new 40 to put on a 18x42 tunnel southfork. leaning towards a merc but want to hear about others that would run better with these new 4 strokes.. 1) what upgrades if any can you do, such as 60 carbs or take off restricter plate or whatever and 2) what would difference between short shaft or long shaft be?

Nissan or Tohatsu 2 stroke 40hp, these are same engine and will be your best bet

they make new 2 strokes?

I am a merc guy, and I would say the new 40 tohatsus are pretty bad arse. Maybe Top Dawg can chime in, he got a nice set up.

it will mainly be used in shallow water/marsh btw..

More the reason to get a 2 stroke in my opinion.

i agree but I was leaning towards a new motor and didnt think they made 2 strokes anymore

I have the new tohatsu 2 stroke. They're fuel injected and come with elect start and power trim. No carburators. Cranks right up and runs strong. If you are running the marsh the 2 stroke will be lighter and cost less than the 4 stroke. The long shaft you will need if you have a high transom. The short shaft for a short transom. For running the marsh you would probably get best performance out of a 13 pitch prop.

yep they still make them, i am running a Nissan on a beat up 17x44 alweld tunnel and it is awsome, these motors have alot of power and are fast.
call Lake Area Marine, they sell Tohatsu...they cost around $5000 setup with stainless prop

thanks guys, any more input? what about durability and long run with 2 strokes compare to 4?

I have a new 40 tohatsu 2 stroke. They are 20lbs lighter, $800 cheaper, and are super quiet compared to older 2 stroke motors almost as quiet as a 4 stroke.

I have a tohatsu as well on my duck boat which is a 2044. It runs 35mph and the fuel injection is great in cold weather. I love it.

You also get 9 mpg out the tohatsu

WOT on a boat? Or is that factory spec? Lot of variables once you out it in a boat..

?????

I am still not sure exactly what I am getting with my 40 hp Tohatsu, but think it is something like 6.5 mpg.

9MPG is on a 1544 custom flat semi v loaded down wot at 38 mph. no special modifications just a jack plate.
get about 8 mpg on 1844 semiv alweld tunnel wot 33 mph.

Nawwwwwwwwwwwweee

TLDI Tohatsu. I've got one and it has been awesome. MPGs are awesome even at 5k rpm.... :)
