Tohatsu DSH changes!!!

[mercguy]

please consider SERIOUSLY about changes the prop shaft depth requirement, as it definately is a handling (safety) issue!!!!!! If this does not get changed, expect a few of the current Tohatsu DSH racers to go to DMH to get away from the height issue!!! PRETTY PLEASE!!!!!! Also, please allow the use of "any type of material" aftermarket reed valve.....................thanks!!!

write it up

I will get that done this weekend!! Cause there AIN'T NO WAY I am gonna risk wrecking my BRAND NEW DARNEILLE DSH due to handling problems related to poor propshaft depth set forth for the Bass Tohatsu by the DSH parity committee.

Aftermarket Reeds?

So Darren is the reed issue a fatigue problem or something else? I have heard some rumors of this occuring (sucking a reed), what kind of data has been compiled to support your request? Just playing devil's advocate......

[mercguy]

yep..........

just as you would suspect from a steel reed in this type of engine. And also and cost-saving measure (so when the steel reed decides to break, it will not do serious internal damage to the engine, like a fiber reed could prevent.).

I can't resist

Doesn't common sense come into play here ? If I had one, which I would not mind having, I would put the fiber reeds in it anyway. I would also run a depth to which was safe. I am not crazy enough to go out there racing at 78 MPH right next to someone and have the boat go wild.... duhhh. Does someone need to get killed or seriously injured before anything happens ?

I hope this issue gets on the agenda to discuss at the meeting at the very least.

Or, grow DMH !!! Sounds like a very cool idea to me !!!

It will be on the agenda, no doubt for safety reasons. That said, I hope the parity committee has enough data from somebodies testing to compensate for any speed differential. Somebody needs to test the motor thoroughly at a safe height and still maintain parity. John 2-Z

Sounds like to me the engine should be marketed w/carbon reeds.

[mercguy]

I believe that is the plan, once they are approved by the SORC. But, being that Bass is basically the manufacturer, they "should" be able to dictate what goes inside or outside the engine, according to their specs.

I believe that info has been passed on by a Tohatsu racer..........

I have run my Tohatsu with stock and boysen reeds and there was no change in top RPM. The stock reeds have a slight advantage at the mid range RPM giving more punch. This is only true when they are new! After 5 - 6 races the stock reeds begin to weaken and the performance of the engine begins to fall off. That is why Sid and I change the stock reeds to Boysen. And for the protection of the motor.

The SORC should have no problem with changing the reeds. Make a proposal and give it to your commissioner. To my knowledge this has not been brought up before the commission. John 2-Z

Good Info!

This is the type of info is useful when making such a request to the commision.
