Re: 540 wont start.

My suggestions are simple, confirm if the mags are producing spark, use an inductive timing light or an in-line spark light to confirm. If no spark, pull them off and send out for a refurb. GMAC76 is a good option, he will get you back running quickly.

Re: I'm Building 2 Stossel Boats with High Torque Motors

This was intended to be a quick turn around, old school Stossel build, but those old school seats are pretty damn comfortable. I felt very comfortable in the seat and those bumbs were not jarring my bad back. My back actually feels better tonight than the last few weeks. :thumbleft: That said, I hav...

Re: I'm Building 2 Stossel Boats with High Torque Motors

Went to scout out the river today, she loosens up real nice in the tall grass. Slides easy in the morning dew, went everywhere. Dry maiden cain and that damn sticky red heather seem a lot less sticky now. Here's the last 1-1/2 mile run back to the truck, all dry and high noon sticky. Turn up the Bos...

Re: 540 wont start.

Ted,
Your switches ground out the mags to shut them off. You do not send power to the mag, it makes it's own. Mags ungrounded=live. Mags grounded = off. In either case there should not be 12V on the wire ("P" terminal wire).

Did you check for spark at the plugs?

Re: Advise for buildin aluminium hull.

It is fine to adjust the engine angle, just don’t add a big plate to the stern. You should be able to sort it all out by tweaking the hull, prop/engine angle and weight distribution.

Re: Advise for buildin aluminium hull.

But before trim tab, I want to try tune of the engine angle again. I think my hull have little bit short flat bottom. I have idea for far future try to increase length of flat bottom by 1 feet. I can use for it trial plate with width like flat bottom. Do not do this, it is a bad idea, from your vid...

Re: I'm Building 2 Stossel Boats with High Torque Motors

Gary, It’s an 18 wheeler scale. 8,500 lb truck (both axles) sitting on one portion of the scale, hence the 8,500 lb figure. 2,700 boat and trailer (axle and tongue jack) sitting on the other.

Re: Advise for buildin aluminium hull.

I would think second gear would give the best fuel consumption on the long run, but you are Better suited to test it out and tell us. That’s a common point of discussion and disagreement on this forum.

3rd gear appears possibly useful for off plane idling if you do much of that for bow fishing etc.

Re: I'm Building 2 Stossel Boats with High Torque Motors

The last time I weighed the rig was 2016, it was 2,940 lbs. Hit the scales on the way home from burning Diesel & AV fuel all week. 2,700 lb boat & trailer full of fuel, extra 5 and slimmed down tool kit. So roughly my original goal of a 250 lb diet. https://southernairboat.com/wp/wp-content/uploads/...

Re: Suzuki Hayabusa 1340cc. 197 HP.

I suggest, before doing anything else, add a clutch and gear shift linkage to what you got! It is wise to minimize reasons for going into the prop cage! Your original build called for free and fast running down deep rivers, then running the edge of deep water until you got to your blind for the blas...

Re: 540 wont start.

Put a timing light on it to check for spark. I just tie wrap the trigger, crank and watch for flashing. Wack the bowl to see if it frees up a possible stuck float.

Re: Suzuki Hayabusa 1340cc. 197 HP.

If you want to run dry you are gonna have to run the engine to the max Hp RPM, but a proper muffler should keep engine noise to minimum. Most of the noise is from the prop. To keep prop noise down you want to keep the tip speed down. 2,500 RPM max on a 72-74” prop will be relatively quite. Those ski...

Re: Suzuki Hayabusa 1340cc. 197 HP.

Your torque roll is your output torque at the prop. 400 ft lbs should not be a significant issue unless you are seeing issues now. After thinking on this some more, at 400 ft lbs and 2,500 rpm, a 72” 2 blade probably does work. At 500 ft lbs I get about 2,650 RPM on maximum (#3) pitch on a NGQ. I al...

Re: Suzuki Hayabusa 1340cc. 197 HP.

Moryak, You said you want to use a Q prop, but did not mention diameter. I assume a 72”. At full power the ideal speed is 2,850 RPM. First gear would have a 4.16 total ratio. Second would be 3.09 ratio. Second gear is the best match, putting engine RPM at 8,800, 180 Hp and 107 ft-lb x 3.09 = 330 ft-...

The river is closed between Highway 98 (a couple miles North of 65D) to roughly the Istokpoga canal. The Corps are still working near Highway 98.
