Incredible ! Great job! This screen shot shows base timing @30 BTDC and with those switch settings if I'm understanding this correctly, shouldn't the plateau on the curve only be at 24 degrees?

Consider buying a lay down pipe now and running it with a spray bar on that 61x. You’re gonna need the pipe for whatever motor you do next anyway. And get a Zeel, also usable down the road. I’ve ridden a couple of 61x’s with lay down pipes ran wet and they are actually a blast. Instead of...

I agree that a 144 would be a better match for that 61x. However….. I’m going to bet that hull is setup with 155 shoe, so for less buy, sell, repeat a flat prop 155 makes sense. And that sweet hull is gonna need a bigger motor in the future.

If you’re using that 61x with an OEM 155 a 7/11 or 7/12 is going to be way too tall. I ran a 7/12 in an OEM 155 with an 898 PHP/PFP, for a 61x go as low pitch as you can find, like a 5/9 or 5/10…

In my biz pump shafts are always 400 or higher grade for exactly the reasons mentioned. We have had customers who couldn’t accept the lead time on replacement shafts attempt to copy them with non-harden grade stainless and every one failed resulting in more damage to the pump. Anyone have...

Correct. Get yourself a Cold Fusion tool.

How about additive titanium props…..think they’d hold up?

I use Zoro for business purposes frequently. Where McMaster supplies name brand top of the line merchandise without necessarily specifying the brand they are supplying, Zoro calls out exactly by brand what the are supplying. If you call McMaster and request what they are supplying they will tell...

Just run the Wax V3 curve.

I went back and edited my original post, my flush enters a tee on the front port of the exhaust manifold cooling inlet, not the head. With 4 head pissers and where you’re teeing in your not going to see a lot out of the head pissers, but you’re still flushing out thru the inlets at the pump.

X2 on flushing thru the pissers. On my 61X FS1 I used a bulkhead shut off plumbed to a tee on the front port on bottom of exhaust manifold: Or you can use open non-valved bulkhead disconnects for pissers and flush thru them: It's not critical where you tap in the starting point for the...

X2 on Vacuum test AND pressure test ! Always give the motor a Push/Pull test !

The stuff I'm running for pulse lines is rubber vacuum line I use at work for testing mechanical seals. Have it on a roll, don't even remember where I got it..... It's the same stuff I vacuum tested the motor with. Stays rigid and doesn't collapse even under a perfect vacuum. And pretty...

Thanks for reading! I’m old school and just a coincidence, I’m old, luv build threads. More enjoyable to read build threads than it is posting them, lol.
