Transmission for 3HM35F Yanmar 3 cylindar engine on 1989 IP35

What transmission is it? We have a 3JH2e Engine with a KBW10 transmission with a 2.83 gear ratio. My friend, Jeff on Lucille has this engine but I do not know what the transmission model is. Once you know that, take a picture of the transmission plate then you can easily read it and have it for records. Once you have the make and model, I would call Bacons Associates in Annapolis, MD, they sell used items and maybe they have one. Repowering would be very expensive just to fix the trans.

I too am working through a rear engine seal and we have a small leak of engine oil, not red ATF trans oil, that is getting to the shaft coupler and then leaking out between the coupler. I will be pulling this transmission and replacing all engine seals and then lucky for me, I have another KBw10 trans that will replace this one.

So, I will have my old one which is working fine except for this oil sea engine leak. Do you need a KBW10 with a 2.83 ratio? If so, I could sell you my old one.

I have emailed this to you but i wanted to document it in the thread as well. Mack Boring has access to only 3 KBW10 transmissions on Sept 2011. They were surprised that they could find any. These are no longer made and will be harder to find as time goes on. A new one is $3200 and to rebuild a basic service on on is $1100. Most rebuilds will need more than just oil seals, so the clutch will need service and i did not get that price.

So, if you need a KBW10 transmission, you better act fast!

I would look into proving that your engine is shot by doing a compression test on the cylinders. If that is bad, then I would next inquire with www.mackboring.com/ about rebuilding my engine. Next I would inquire with them about a used rebuilt engine and transmission. If all that does not work out, then I would look into re powering with a new Yanmar. Be aware that the new motors require a 3" or 4" exhaust,(yours is 2") so your old muffler and stern exhaust will need replaced as well. The larger horsepower is nice. We have the 3JH2e Yanmar on our 1994 IP35-#165 and it is plenty of power.
