Need Tohatsu help

[Larry M]

If the motors are exactly the same they will run the same. The problem is that getting them the same is almost impossible.

Same...

Yup, I'm with Larry.

Ain't no magic dust in there, just attention to detail.

Talked with Alex today....he gave me some more tips on what to look for......dave

I know zip about the motor. However, could it be a cyl sleeve problem?

[daveracerdsh]

Motor

It is very possible there is something internal....could be a twisted crank, sleeve problem, you name it. The crank is pressed together..something I am going to check when I get back from a short vacation. Dave

It has been common practice to tack weld pressed together crankshafts on performance Japanese motorcycle cranks. Should this be done with the Tohatsu as well? I don't know much about them either but I am going to win the raffle so I better learn.

Make sure you don't have one of those squeeze bulbs in your fuel line. How many times have we seen people chasing gremlins and to finally eliminate a faulty bulb/check valve that was restricting the fuel flow ! Also check all fuel lines for restriction. Always check the cheap and simple stuff first. JGW 1CW

I will second that. The first race I went to with my D mod they told me to get rid of it..Causes nothing but headaches

not so fast Glenn...................if you use a GOOD primer bulb (OMC makes the best ones), you will not have those problems....people that use the cheap ass bulbs (Tempo, Sierra, Napa, etc) will have the problems...............I use OMC primer bulbs on ALL my motors and have NEVER had a problem with them and either have all the rigs/boats (hundreds of them!!) I have set of with them either...............if they will survive behind a 300hp outboard, then our little 60hp and less motors will not have a problem either..........as they as they run a vacuum operated fuel pump.

its when people use cheap ass ****, is when they have problems......................

Squeeze bulb

I used a Tohatsu squeeze bulb..worked fine until it was involved in an accident. Now I use a Shrader valve and pressurize the tank...works fantastic

Not so fast Daren.... Your primer bulbs must be really old because "OMC" is no more! Its BRP now and there bulbs are OK in my opinion. The no fail bulb would be Honda! I sell hundreds of BRP and Honda fuel lines every year and Honda wins! Why would anybody want to run a restrictive valve on a race motor anyway??? I don't sell very many 300 hp motors, but don't they all have the same lift pump pressure? I do agree on the aftermarket stuff, its pure garbage they will all fail! Just had to share my professional opinion and experience.

I’ve found that if you squeeze the throttle all the way open, it will run faster… ; )

On a serious note, I’ve heard that the chokes on those things can bounce around and close or partially close sometimes. Maybe a stiffer spring…

Oop's, guess I should have re-read the thread.
