Yeah they mention phasing the map readings in the x-tau explanation, but it was unclear to me whether ms2/microsquirt was actually capable of that. That would be the coolest way to go about if it could I think

I feel like a wide band o2 would be extremely helpful if it gave meaningful readings, for developing the base map, probably tune 0-100% throttle tied to a trailer in the water, cruising down the lake and out of water(won’t hit 100% here) and interpolate between those three lines to fill in your...

I was thinking I'd use alpha-n and I could basically treat it like a carburetor at first that you don't have to turn any screws on to change jets, and get the benefit of programmable ignition timing as well. I think you guys are right about skis not being the best candidate for efi, being a...

There's as much as I could really get away with, I figure I'll run it and if its too hot I'll try to do some tricky stuff to add more. I kinda think even with just that much cold water in it it should stay pretty cool with how fast aluminum transfers heat. Also I wonder on say a factory pipe...

I bought some gp1300 throttle bodies, haven't bought the microsquirt yet though, did a little thinking about how to go about it. In the mean time I did get my cylinders back from powerseal: And ran out the rest of the manifold:

How much do you want for the riva pipe if nickfons isn't interested?

time to switch to shrink fit, well last week was

Maybe I’m crazy but it really looks like you circled the temp sensor wire not a water line

Just being lazy and wondering if anyone knows the bolt spacing of the stock round nose pole bracket before I rip the one off my ski to measure it. Do all the aftermarket hulls use that same pattern?

When I went to school there was a autonomous underwater vehicle project team, I’m pretty sure their competition was finding stuff underwater. I can see if I can get in contact with anyone on the current team but it might be a bit far for them to travel to do some “testing” (Ithaca, NY). Looks...

It’s on my to do list but that’s a long list right now lol

That sucks, my rickter sank 3 days ago but only in 12’ of water. We found it pretty quick but it went straight to the bottom

lol gotcha. I have a wetjet pipe thats already been welded for a squarenose if your interested, if you haven't changed the stock aluminum impeller though that's a night and day difference.

Nice, thanks for reporting back, my buddy just did this swap and I havent ridden with him yet but pretty sure he still needs to do some jetting, this will be a good reference. Did you add it to the jetting database?

Hate to be nitpicky but I think the title should read "WTB 701 motor"

I just figgured a custom ebox that was water tight with some waterproof panel mount connectors would work

I really wanted to put gp1300r throttle bodies on it and run a megasquirt, as that would give me programmable ignition as well. I figgured I would try to get the thing running before tackling that, but sounds like maybe its smarter to try for that from the start

I thought I had seen somewhere why people don't generally use them, but cant seem to find it again. I now have 3 sets from three gp800s I picked up for parts. Is there something I need to modify to use them in a stand up? I read the groupk page that says they generally suffer from a lean...

That sucks, I actually just rode yesterday for the first time in a month also because of stitches in my knee, you would have thought I would have made more progress lol. Have you ridden that ski at all yet? From the few videos I can dig up it looks like the 927 made decent power. There seems to...

Here's the first half of the manifold, got one side barely roughed out then the drive blew: Atleast I put a 155 pump shoe in the amp hull, current plan is to put this motor in that hull.
