    I picked the boats up Wed at like 10:30 pm but have not had much time to measure. One thing I forgot about the TR1 is the airbox and electronics hang off the front. The block is short but the overall package is pretty long. See this video at about 0:17:

    The stator case itself is fairly compact though. But it would suck to need to relocate the entire ebox and possibly mod the harness.

    Yeah, I figured that ebox and air box would add to it. But the TR1 total dimensions are smaller then the MR1. Per a few articles I have read, here is from Boating Mag "Featuring nominally smaller displacement than its predecessor, it nonetheless produces 13 percent more power. It’s also more compact, trimming 40 percent off the size of the four-cylinder MR-1 (30 by 21 by 19 inches versus 42 by 22 by 21 inches). At 160 pounds, the TR-1 also shaves 20 percent in weight." I would assume that is the complete motor including the front accessories.

    I have thought about finding cheap damaged parts for test fitting. If I could source a ruined crank, lower case, and front stator cover I could then test fit using the motor mounts and figure out my coupler situation as well as alignment. That would then allow me to assess my available space up front and determine if the ebox and air box need relocated at all.

    Looks like I've got a customer bringing a 2008 & 2010 VX Cruiser my way for inspection/repairs. (I mostly work on 2-strokes) Was told one "runs rough" the other "won't run faster than 25mph". I'll be giving them a close look while I am doing my work and taking measurements while I'm at it for my own project.

    My day job has been keeping me pretty busy. Those are the 110 hp MR1s. intake, exhaust and oil tank top (its shorter) are different.

    I hear you on being busy. I work as a Draftsman/Survey Tech at a civil engineering firm full time. This is my first spring "advertising" my mechanic work on skis, which just consist of a single craigslist ad. Its pretty much blown up in my face. I've got 4 skis already at the house, the 4-strokes coming tonight, 2 ZXI 1100s scheduled, 3 Seadoos skis and 1 boat scheduled. Plus the 8 skis I currently own myself and the LS2000 waiting for me to get time to drop the motor back in. I've not had a free minute during daylight in about 2 weeks. Its awesome but very stressful at the same time.

    Finished up my work on the two VX Cruisers that came in for maintenance over the weekend. Afterwards I took some quick measurements. From the furthest rear engine mount bolt to the farthest front engine mount is 24" exactly. Interestingly enough the two skis had different driveshaft setups. The 2010 had the normal wall behind the motor that the intermediate shaft mounts to. The 2008 had no wall behind the motor and the driveshaft bearing housing mounted to the hull of the ski. See attached pictures.




    The motor itself is roughtly 30ish inches from the front exhaust pipe to the rear of the motor not including the coupler. On the 2010 it is 35"-36" from the intermediate shaft wall to the front exhaust pipe. Just going off those measurements I think it would be a heck of a task to get the motor to mount up to any kind of intermediate shaft setup in my boat. I knew motor mounts would be needed. But there simply isn't enough room between my front and rear walls. Remember I have roughly 31"-32" before I have to start cutting into the walls.

    From here, it looks like I need some TR1 measurements. Those "should" be shorter motors. But there is a lot of ifs with them.

    In other news I've got the replacement 1200 reinstalled and about ready for testing. Need to finish up some repairs on the pump side of things then button up the motor install.

    Yeah I see exactly what you mean. If you have a tape, I wonder what the length is from that small "wall" the intermediate assembly mounts on to the front of the air box/ebox? It definitely looks as long if not longer than a MR1 in total. Maybe the Airbox and Ebox can be relocated?

    i know this is an old post... Im just about done with LS2000/LST1200 AR210 conversion to MR-1 HO's... the engine bay is 5" too short to accommodate the MR-1 HO's... I moved the engine bay front wall 8.5" ( to allow service of the mid bearing) forward of its original location, added a 3/4" bulkhead/box to carry the engine mounted adapter plates that I machined from 316L stainless plate... Note that you will only have room for a 10" wide fuel tank in the original location at ~29 gallons rather than 45... I chose to make that space storage and move the fuel tank forward to the Ski locker where I am putting a 66 gallon ATL super cell bladder tank... for what I have in the my boat plus the conversion you could buy an AR230 HO but then you would be stuck with boat that is nearly 2000 lbs heavier and wont run like a scalded cat in 12" of water... or lift on davits without a ton of mods
