I have used several SDS systems. Very basic. Very impressive performance. A carb motor might run on top with an injected motor But the midrange and bottom end are totally new, and consistant!! Runs...

Impressive!! I have done a few injected v6 omc's. Lot less burned pistons. Keep us posted.

Outboarder on this site has done quite a bit with this. And i think Cheney has done the same. These guys may have some insight?

56 inch omc, porte, head cut, tuner, unlimited pack. I will be running plastic reeds. Do I run reed stops or not? I hope to spin the snot out of it. Personally I have never run stops in my motors....

MERCURY? What is the old saying - If you wanna go fast buy a merc, If you wanna get back buy a Johnson!!

I am definately using this boat as a play boat. I just hate to add all the weight. I just Need to get to the sandbar! God forbid if I have to be towed home by a Mercury!

I recall Bill Gohr mentioned that. Anybody know about it

I want to oil the bridge on my 56 inch omc cylinders. Can somebody help.

Will the light 65 hp flywheel fit a 56 inch motor. Clearance is not a problem. Worried about timing.

The 49" plate measures 1.75" the 56 inch plate measures 2.075" you are giving up .325". This still leaves .800" of engagement and the o ring is still inside the crank!! Is it the right thing to do? I...

Tim Can you cut a head for me.

Tim I have always drilled an 1/8" hole to spray a small amt of water on to the tuner. No paint problems on the v6's. Is this going to kill mid range on a little motor. I have done what you are...

String steering is holding the powerhead solidly in place by the arms they are bolted directly to the midsection.with the tiller and conventional steering torque is transmitted thru the upper motor...

Thats where i got mine He did a beautiful job on them. You do however have to add a center hole for the 56 in adapter.

Here is the one I built for mine. Built to the sst60 spec.

I am building an 86 56 CI omc motor for my new Allison 13. 15 inch mid nitro gear case with nose cone and lwp, Custom tuner.150 PS I head. Thinking about drystacking the adapter and diverting the...

I can get one!!

Yes the motor runs high and has no problem with water, 22-25 psi water pressure. It only breaks loose on tight turns when pulling a water skier. And then only slightly. my daughter weighs 115 and I...

Thank you!!

I run the propshaft 2" below the bottom of the boat. The 19 runs 41. The little yammi runs 46 at 6000 rpm.

New toy. Allison 13R .56 in motor on 15" mid with nitro case and lwp.

I have the same setup. The 13x19 works good. My fastest prop is a 11x21 yamaha 4 blade. The boat wants to porpoise as you jack the motor.

56 inch omc. 1986 block. looking for 150 + or - psi compression. What do I need to cut the pocket depth on the head to??

Does the carrier on the nitro case Ned to be pinned when run on the surface. Don't need to spin it in my brandy new unit!!

Big horsepower and reliability? Good luck with that one!

THANKS!!! Gonna build my own tuner if I dont find an sst 60 adapter

what are dimensions of the sst60 tuner. I have the lenth 7.69" anybody know the dimensions on the outlet??
Thanks.

Need an unlimited power pack for OMC 70 triple. 1980 Ignition. My pack is an aftermarket unit with an L at the end. Which one do I need?

I use 3/16 x 5/16 tygon tubing

I just purchased one. It is untouched and in good condition. I have however, spun modified v4 flywheels on a v6 to 9000 rpm without issues. Had better luck with the yamaha ignition on the v6. I used...

Stinger,
How much weight did oyu take off what is the diff in the two?

Was yours turned down on a lathe. The ones I am finding have a groove for a starter rope.Maybe I need to keep looking!!

If you use an electric fuel pump you need to regulate the pressure so it does not go past the needle and seat. That will just flood the motor. Why not jet the motor. Jets are not terribly expensive!...

No , not on a set of race reeds. We would change them ea. day on the drag motors. But a set of sport reeds will last a long time if the motor runs smoothly.

You should not tear them up that quick. was it popping back through the carbs? I usually get a couple a seasons out of a set.

is this part no 580810??

the drag reeds will be thin and short lived but respond well. You will be best of with the sport reeds if you are playing with the boat. Chris is a good friend of mine . He will lead you straight!!

decals came from e bat - nanas decals. yes I would like the color code if you can get it.
Thanks
Don

What is the blue.The color is supposed to be performance blue but my PPG guy needs a color code! Did you do the blue on the sides in vinyl or paint.I have all the hustler and the evinrude decals. by...

Looks great!! Mine has a long way to go!!

Tim Any luck finding those carbs . I could use a whole set if you come across them. Probly work good with one of the exhausts you are workin on.
Don

The only no I could get off the carbs was -EN432989. The tags are long gone. But they are definately three jet large bore.
Don

Does any one know the color of the blue on an evinrude 75 hustler. I heard once that PPG had cross referenced colors.I would like to shoot the paint in base coat /clear coat.
Don

both sets are 2 jet 1.187'. I have two 3 jet 1.25" carbs on a twin I built but I think I better run 3 carbs. I sure do like them for tuning.
I

I have two sets of 70 hp carbs. Is there an advantage with the 75 stinger carbs over the 70 hp carbs. Am running on a 15' mid with nitro case . I have a set of 75 carbs buried in a box somewhere.

Any updates on your exhaust ?

Guess I will be looking for a complete mid. might just sell my little motor as a complete unit.
