I picked up a old 1987 procraft with a johnson gt150. My first boat.. I only used it 3 times in the fall. But put alot of miles on up and down a river . Seemed to run fine. Getting ready to put up for winter I noticed water coming out of the bottom of the exhaust cover. Looking online, i see the inner and outer exhaust gasket, which I will buy. My question is what would cause this beyond just bolts loosening up? Will or would it cause damage and what should I look for or inspect?. Hopefully it will be just some gaskets and all better... hopefully. .. also... does anyone know the rpms at wot? Seems like I should be going faster than 45 mph.
Thanks
