thanks for all the infor, it is indeed an xr-4 on a 17 1/2 procraft. I told him if it run that it should be a quick boat. I appreciate all the responses. happy trails
thanks for the info, i knew that the exhaust went though the lower unit but i figured that the prop would feel warm too, i just put new fluid in it about 2 months ago, i will check again though. thanks for the info
