Re: Nissan - Tohatsu 18hp
Well I just bought a 40 hp Tohatsu from my local dealer, I asked him if I should bring it in for a checkup or anything after a specific number of hours, he said just follow break in and run it.<br /><br />He said if I felt more comfortable, bring the engine in after I mount it to the boat and he will start it up and do a general check. <br /><br />So to answer your question, from what I can you just need to follow the break in guide and I think at 10 hours they recommend you change the lower unit oil, and they give you great directions on how to do that. Otherwise these motors seem to be pretty maintenance free (besides the givens).
