Re: Hydrofoil

Porpoising can be helped a couple ways. FIrst look at the bottom. If there is a rocker (hull bent downward, toward the water) in the last 3 or 4 feet of the back side of the hull, that will cause porpoising-guaranteed. Run a straight edge longitudinally (front to rear) across the bottom and see what...

Re: Livewell

I assume you're speaking of black bass and tournament style fishing. that's a loaded question that has an answer of "maybe". How big are the fish? What's the temp in the well while on the lake, and what's the temp when they're in transport from the ramp to weigh-in site? The hotter the well gets, th...

Re: 1990 Suzuki 40 skip at WOT

Could be a few things. Start with the easy stuff. Look up inside the pump and see how badly the impeller is chipped/worn. Check the clearance between the impeller and then housing, it should be 1/16" or thereabouts. If it's really loose, you may have to re-shim. If shimming is not possible or the im...

Re: Best repowering for old boat?

Yes, indeed, there is a power stroke on every revolution for each cylinder. BUT what they don't tell you is that there is only about 1/2 the torque produced per cycle, so it ends up nearly a wash in the end, with some unburned oil ending up in the waterways. That's why some areas have outlawed 2 str...

Re: Best repowering for old boat?

what is the allure of the evinrude (BRP)? It's no lighter than yamaha. It's HEAVIER (by like 15+ lbs) than the standard yamaha 115. It's 2 stroke, meaning you have to add oil to the tank periodically (more stuff to do). Why spend more money on it when you can get a 4 stroke yamaha which is a 4 cylin...

Re: Jon boat advice

Bad part about a jet is that the best performance happens the day it's bought new. As the impeller wears, performance drops off until the impeller and sleeve is replaced. Then if you are planning on running in shallower mud bottom areas that have a lot of trees nearby and/or a lot of vegetation in t...

Re: Small Engine Projects

When I was younger, small engines were my "thing". Then I took a job working on small engines, and here it is almost 30 years later, I could care less about them once I leave work. But of many small engine projects was a home-made airboat. 1432 flatbottom, 3 seats. Rear seat, had a swivel screwed di...

Re: Prop

Solas aluminum props are made of a real thick cast material. Thicker blades=more drag. You'd think being thick, they'd be strong but I haven't seen evidence of any more strength than the factory yamaha props that people like to replace with solas cheapie aluminum. When a blade breaks off, look close...

Re: Additives - Ring Free vs. StarTron?

As a yamaha dealer, we see TONS of solicitors come through trying to "dis" ring free. I mean at least one a week, more often in the summer months. The star-tron guy came by a while back trying to peddle his stuff. He had a glass jar, asked me to put about 1/2 qt of gas in it, then he put a few oz of...

Anyone have real data on RPM difference between the Yamaha 11 1/4 and the 10 1/2 pitch props.

Yes. On mine it's about 300 RPM difference.

Re: EFI and Carb motor storage?

kdgrills has it right. If you go by Yamaha's manual, it should be fine. It's advisable to run ring free plus in the tank all year long; and at the end of the season your VST (vapor separator tank) and injectors will already have stabilized fuel in them so really all ya need to do is fog it (per manu...

Re: 20hp 4stroke on 16' Jon

I've put a few of the 20hp Yamaha's on 16' war eagle boats. They are heavy (the hull). Most people don't mind them. The boat is rated for 40hp. I ran a 15 on mine but it's about a foot shorter in length and a little lighter. Little sluggish getting on plane but it did fine, ran 23.6mph. You can chan...

Re: Prop

That 10" solas is where I'd be if I were choosing between those 3. But if you went with a turbo or even a Powertech, you might find another mph or so. Big deal. If you have access to one in a 10", try it. Also, if you have access to the Yamaha 3x9 7/8x10 1/2, you might try that-they are VERY good. A...

Re: Carb versus EFI 9.8/9.9 4 stroke

Being that I work with outboards for a living, I can tell you the difference. A carb motor--if it sits a while, you WILL be cleaning the carb. The jets' orifices are so small that they plug easily. EFI? "Mostly" a non-issue. That said if they sit a while, like years usually and it doesn't run the ne...
