building a sport hydro 40 that needs power. looking into .45 ops and os max .46 not sure which one to use. i have never raced just the occasional weekend warrior. which would be better?
They are both good engine for sport use with medium nitro (about %40). Go with the one in which you can most easily obtain parts.building a sport hydro 40 that needs power. looking into .45 ops and os max .46 not sure which one to use. i have never raced just the occasional weekend warrior. which would be better?
OPS hands down!! got way more power and RPM's then the O.S max.46. I'd remember there was proublems with the O.S max.46 splitting at the bottom of there crank case. Thats what I was told. Theres a OPS dealer in CAN.building a sport hydro 40 that needs power. looking into .45 ops and os max .46 not sure which one to use. i have never raced just the occasional weekend warrior. which would be better?
OPS is still making the marine engines.Both are good engines for sport use. I raced the OPS 45 engines for years. I was racing an OS 46 more than 30 years ago at a District race in Oklahoma. The boat was going down the front straight when the engine stopped. The top of the case was gone. It had split just above the motor mount and the upper case and sleeve went for a ride. That is when I switched to OPS. I think that parts are still available for the OPS 45.

the funny thing here is that no one asked him which os .46 vrm or vxm. im not a fan of the vxm but the old vrm ran great right out of the box. i never broke a crankcase and ran 50 % nitro threw it.building a sport hydro 40 that needs power. looking into .45 ops and os max .46 not sure which one to use. i have never raced just the occasional weekend warrior. which would be better?
I think he was referring to the VXM since he mentioned about ordering from Tower.the funny thing here is that no one asked him which os .46 vrm or vxm. im not a fan of the vxm but the old vrm ran great right out of the box. i never broke a crankcase and ran 50 % nitro threw it.building a sport hydro 40 that needs power. looking into .45 ops and os max .46 not sure which one to use. i have never raced just the occasional weekend warrior. which would be better?
