    OMC V4 motor weights

    I see the 90 and 115's weigh around 315 lbs but the 120-140's weigh 375 lbs.Whats the difference in these motors?i thought they were basically the same except for the degrees of angle(60 vs 90) and bore and stroke sizes.Is there an actual weight difference between them or?

    so there really is 60lbs difference between the two? Is it me or is it really tough to find a decent motor in the 300 lb range,that makes around 115 hp.inline mercs and 115 omc v4's seem to be the only two options

    There are no modern or even semi-modern engines in this range. Sucks, eh?

    yea but i heard it's kinda doggy and more like a 80 hp.I think there is some after market support for it though,so maybe the oomph can be put in it?

    You mean a V4? That would be a hard to find item. As are used V4 parts as I'm now finding.

    Early v-4 crossflows weighed in between 300 and 310. These were still made until 1996 as 88 to 115 hp. Generally, parts are still readily available for these engines. The 60-degree loopers were made starting in the 1997 range, weigh in at 349 and produced 90 and 115 hp. They did make a 120 and 140 hp 90-degree looper in the late 80's through mid nineties that weighed in at the 375 figure. The 120/140 were larger displacement and much beefier than the original crossflows.

    Find a late 80s 110 xflow v-4 you will be happy with that. It is basically the 140 of the 70s. I have one modified and has run real strong for 6 years. I have beat the snot out of it and it still runs. Pushes my sidewinder to 62 gps. Rick

    120, 130, 135 & 140 hp 122 CI Loopers

    Weigh in at 365 pounds (as per OMC specs), they are heavy for a 4 cyl but they have gobs of power and torque. I had one on my Stratos and turned a 25" Renegade 4 blade @ 5900 rpm. From what I have read and seen they can be modded to the hilt. Just like 1badaction stated, check out MAD EFI (Wayne Taylor).
    I think 1984 was the last year for the 140 OMC X-Flow, starting in 1985 they re-badged it the 110 (due to rating horsepower at the propshaft), then later the 112 and 115. They are a very good/durable motor and I would think parts are everywhere for these (you see them everywhere here in Kansas).
    Another consideration is to find a Yamaha 115 or 130 V-4. They still make the 115 and quite producing the 130 a couple of years ago. They are heavier than the OMC X-flow's yet lighter than the OMC 90 degree loopers. In the early 90's they made a 115 Pro V that was supposed to be a little hotter (125-130 hp) than a regular 115. Hydro-Tec makes HP stuff for the 3 cyl 90 hp Yamaha, and all the V-4's and V-6's.
