Post Motor Comparison
Obviously people run different motors for different reasons. I have had mudbuddy and gtr. With that being said, what stands out to you guys about each mtor? The 37-40hp class. Assuming they were all mounted on the same hull, which is faster, smoother, turns sharper, most reliable, lightest weight, best reverse, and finally - cheapest? Or are they summed up the same as ford vs chevy behind toyota of coarse?

I completely agree. mod v vs flat, .100 vs .125, floatation vs non, big blade vs raptor, bps exhaust vs stock, etc.... Too much going on to get a decent evaluation. That's why I prefaced it by saying it wasn't a fair assessment and ended by saying that I would try another GTR before making a purchase....

Nevertheless, I found it an interesting comparison as to what a difference in hulls and props can make. Maybe we'll get bored this winter and swap them out and see the differences. That would be an interesting comparison....

I had a 15ft triton mod v with a mb 23 on it and it sucked ass. I don't know if it was the boat or the combo.. I bought bothe new and you literally had to get your partner to take a shit before he got in if you wanted to stay on plane. I have mixed reviews on my gtr.. It never let me down but it had some problems.

Something has to change soon.. We spend thousands chasing 30mph.some mf is going to start building a 50mph motor that won't sink a barge and get rich as shit. Gdam lawn mower motor on back of my boat... Smh

If it runs 50, we will pay! A 70hp 3 cylinder outboard is just under 1000cc. My 250 merc is like a million billion cc. Yes, we will finance and pay! Lol

Transom angle doesnt matter like everyone claims between the big 4. It matters when digging, or trimming up (total range of travel for trim doesnt change based on transom angle). The angle of the transom only affects the angle of the transom mount, and as such the prop angle at the top and bottom of trim range. Purpose of your trim is to adjust the angle of attack the prop has on the water. The transom angle doesnt. Transom height matters far more (and is affected by that angle depending on how the builder measures transom height) and the height the motor manufacturers recommend is a good rule of thumb, but actually can be tweaked to get better performance depending on the boat and frame.

Last time it came up, the kawa folks weren't interested in the mudmotor market because it's so small and we're rough on these things. The investment isnt worth it to them. They freaked out by one gentleman that was sending questions about rev limits and other stuff through his stateside sales rep to them and they wouldn't answer. He had a liquid cooled 31hp small block kawa (824cc I think) pushing around 63 hp on his bench. Never could get the build parts and cam information from him to build my small block kawa, though.

Maybe the canadians are worth taking to...

Yamaha came out with a couple small block vertical options last year I think, if theyll make a larger one there would be a couple experiments, I'm sure. Maybe they're in development.

The big Kohler was written off pretty quick from what I saw due to weight and lack of improved power, but I bet a recipe for that one could prove to compete with the Briggs, and the smaller kohlers have proven to hold up to our uses and be quite good little engines. Kohler didnt seem to push it, though, and no one I'm aware of went to the effort of seeing what it was capable of. Maybe worth fooling with for the adventurous fella with a little money, knowledge, and time to throw at it.

Motorcycle engines didnt catch on for a couple reasons, I believe. The first being cooling and weight. No one that experimented with them ever came back with positive or even negative results for whatever reason. The second is manageable power. The harley based longtails that arlon made weren't exactly safe for normal longtail use. No manufacturer ever released one on a surface drive that I'm aware of.

Briggs is the only engine manufacturer to ever at least attempt to keep us happy, though sometimes I question the word attempt with the inconsistency they give us in these engines, but at least they're trying.

Vw has a flat 4 1600cc that is interesting, and a cut down version (a half) that is used in small airplanes that might be worth visiting, but it's a bit heavy and would require solving the cooling issue since we aren't constantly moving with enough speed.

Sucks to hear that, Russ. I think a properly engineered V4 would be an awesome candidate. Good low end torque with decent rpm capability. I guess we should be thankful Briggs has stepped in and gave us an application specific engine, but the opportunities are definitely there and could potentially sweep the market.

It's interesting to hear some of the attempts that have been tried thus far. Eventually some bayou fella will get aggravated with his set up and put something together that will blow us away...

Blah.. Transom angle can be changed with a shim anyway. When i 1st started duck hunting i had a 9.5hp on a 12ft boat. You could show up 30min before shooting time and have the best spot bc almost no one duck hunted. I was like who the hell would pay 5 grand for a duck boat? My last rig was 20 grand, give or take. Its a growing hobby. More and more every year. The motors will get faster and they won't be made by briggs & crappon.
