20" or 25"?
 

Can you guys tell from the pics if it's a 20 or 25?

Sure looks like a 20" ...

compression on the 185hp
 

The compression is between 72 and 77 on all 6 cylinders. Is this OK?

NYMack... how about that T/T? I have the electric on the throttle and under the cowling, but missing the T/T entire assembly, including any wiring harness that may be needed. I can drive down to pick it up.

wow it's runs um suprise that's super low compression. i don't know if i'd waste money with a v6 tilt trim unit for it when it has low compression. you will need a V6 tilt trim unit. not one off the V4's unless you have a press and lots of time plus extra money to convert the mounts and bushings to the V6 style. if i remember correct NYMack's is a V4 unit.

that's a 20" motor. compression should be 115 min to 135 max on each cylinder.

Someone on Iboats said that the v6 was a low compression engine. I still don't know what should be expected with that, though. Regardless... does low compression mean time for a rebuild or are you suggesting just to part it out & move on with a replacement engine?

check it with another guage, you could have a bad gauge. I look for consistancy between the cylinders. The odds of all the cylinders being worn out the exact same is pretty rare, it could happen, but it would be rare. I think Skools had one that was low on all the cylinders. If the 185 was a comercial version of the 200, it would come with the low compresion head gaskets, that would effect the compresion as well.

yeah i have one that has near 2500 hrs and it is suppose to be 140 psi and it has 77 to 80 on all cylinders.
