I was wondering if anybody has done this never seen it mentioned.

I am interested too. I talked to a respectable source and they told me that moding a longtail 35 would make it tough to hang on to. I would like for mine to run loaded like it does empty some what. Not trying to break any speed records!

Exhaust is common, Heads on the 35 briggs are always helpful, via leaking valves etc. I have seen where guys put a minkuni on aswell, helps with idle and some speed. As for the rest I'm not sure, the 35 swomp I drove wasnt bad to handle, now you are allot of power. ... might be a handle full, but you can always throttle down, and Throttle up when you need the extra power. But I haven't owned a Longtail tail in years, so I'd research some more before you dive into it

With no gear reduction, the 35 LT, if modded, will probably not gain too much. The money on that kind of enterprise IMO would be better spent on a stock 35 surface drive which will be 5-6 mph faster top end from the get go. From what I read, most 35 LT owners get low 20's with a hunting load and I would be content with that.

If you turn more rpms you will gain speed, now how much speed that is on an lt I'm not sure. The extra power wouldn't hurt when carrying a load though

had a 35 SS on a 1846 boat I built stock was about 22 mph added single carb about 25 to 26 mph then I pulled heads shave 40 thousandths add stainless valves from pvt and pvt cam with 9x9 hill prop it would run 29 all day bumping 30 empty. I lost a lot of bottom end with pvt cam so I went back with stock cam so I would have some grunt. if I bought another Backwater 35 I would definitely add single carb again and probably have heads done. hope this helps

Saw a mud buddy SLT with the Black Death engine mods. Never saw it run but I imagine it would be a bad little motor
