i noticed that this subject had been noted before, i would like to see how to avoid it in the future. i too had an oil cap blow off due to an over heat of my 20 horse tohatsu. i live in south texas and fish in the lower laguna madre, salt water, i was running shallow but not too, however, we are having extreme amounts of floating grass this year, and i think this was the culprit of my over heat. i have it now at the dealer and they are waiting for a part, two weeks now, from japan in order to get me going. they said that all looks to be in order. they opened the whole back half of the motor and said that all looks well inside. i feel a little unsure, however; i dont want this to happen again!!!! is there a water temp guage i can get for this little motor to help with this in the future? what else can i do to avoid this happening again? since i got this little 20 horse, i have had nothing but problem with it. carberation, sluggish, cowling keeps coming off, seal on cowling allows water under the cowling and saltwater all over the motor. any suggestions would be great!!!!
back to the oil cap issue, i had checked my oil and had to add some at one point. it was then that i noticed the oil cap had already been melted to some degree in the past, i am a second owner, so i had been watching it very closlely when this over heat happened. i am also experiencing a lot of surging after i have been running for quite a while. much like i have a spun hub on the prop. put another prop on it and after running a while i shut down to fish. when i take off again, it is then that is will begin to surge. it doesn't do it on the enitial run from the ramp to the first stop. i am thinking this also may be due to grass.
sorry for all the confused problem sharing, i am just so frustrated with this motor. thanks so much in advance for your advice, skloak
