Powertech SRA is an outdated, high rake, bow lifting prop that takes a lot of power to turn it. On a 2 stroke they worked just ok, acceptable. They were fast top end but getting out of the hole was pretty sorry in my opinion. On a 4 stroke, not so much. There are better options now...

yup 7 atdc is about right. Plus or minus 2 is fine, perfectly acceptable. First things first though. Need to verify TDC on the pointer is actual TDC on the engine. You'll do this with either a dial indicator or a piston stop. (Google it). You can use a dial through the plug hole on #1...

There ain't much difference between the Tohatsu 30 and the F25. 5 hp. But the Tohatsu weighs more, which helps offset some of the 5 additional horsepower. Personally if it were mine I'd look at either reducing weight or redistributing it. Then if you don't already, try a 4 blade prop--you...

how much noise and fuel usage can you put up with? Both are considerations, and even moreso with jets.

as i suspected you need it to be propped such that at full throttle normal load, you want to be as close (or maybe a hundred over) maximum recommended RPM. Lugging it will make oil, cause overheating, ring and piston carbon fouling, etc. Exactly what I'm seeing in those pics. Might try to...

i put you on the list.

factory pt&t while nice has it's limits as you will and are finding out I would have liked to have it too but it wasn't available, unless I ordered a remote motor and put a tiller on it, and in 2017 they were long shaft only (and I need short). So I just hung a CMC on it. Wired in a handle...

Mine is an F25SWHC, 2018 (basically the same motor). Just did the pump on mine due to some sand ingestion. The o-ring you speak of is not normally part of water pump service. The only time you have to deal with it is if you remove the drive shaft bearing/seal holder assembly (#17 on the parts...

we just used hydroturf in ours, because I had it i don't have that issue, it stays clean. Fish slime washes out easily. dunno if its the difference between materials that seadek uses or what? interesting! Thx for posting

you can keep your two strokes until you can't get no more parts for em I'll keep my 4 stroke and enjoy the lack of fuel usage, quieter operation, and overall better experience. I dug my old 25 2 stroke (3 cyl) out a while back and tossed it on, run it around the lake a little, and as soon as I...

yeah a well-known manufacturer (where I bought my boat) advertises .100 ga aluminum. I called him out on it and they changed their marketing. The reasoning is that "gauge" is a term that most people recognize, saying 100 thousandths thick aluminum doesn't mean much to most of the general public

Pontoons. Yes. They are the hardest on outboards. You need data. What's the maximum RPM with a normal load? It needs to be close to maximum recommended by the manufacturer. Most builders will prop them such that, if say the max is specified at 5000-6000, they'll prop them so that they...

So you got it running, then took it back apart? Maybe I misunderstood. Still say a manometer is required...I've done them without, F40's and F50's both (LOTS of F40's both 3 and 4 cylinder) but using some sort of manometer to adjust each carb perfectly (+/- 2 inches of mercury) yields a much...

I've never owned a riveted boat that didn't feel like a big flexible metal bucket-especially when running on plane in any chop. I can be sitting in the back running the tiller motor, and any wake, look over the front of the boat and watch is flex. Port to starboard, or vise versa. Or...

Probably ECU and impeller but I am not 100%. i would not expect there to be a huge difference between the two, considering it's a jet
