Hi to all first of all, haven't been on here in a while, haven't been using boat much, sat for 12 months. never had problems at all till now. 300hrs on motor saltwater used all of its life, took it out yesterday, as usual started right up, put it in the water let it idle for about 25 min. temp 130 took it out for a short trip 3500 rpms for about another 25 min. no problem. went for another trip, about ten miles of running at 3800 rmp, temperature rised to 220 deg. shut her down about 3 min, started back up and temp came down, then it started to go up again 180, shut her off, started, made weird noise, so I checked oil o.k, out drive o.k, started up o.k 1000 rpm temp 140 for about 10 min, then 2000 rpm for another 10 min temp 140... got back to camp. sat for an hour went for 5 mile trim 4000 rpm ran at 140.... what could have gone wrong, changed impeller last year, oil, and outdrive oil too. no water in oil, from overheating, seems to have the same power.
for being saltwater used all of its life, risers and motor look great. all original never changed riser or manifold.
where should I start looking or testing. want to keep the cost low due to economy but want to keep boat running great again...
could weird noise be because of overheat, sounded like a bad motor for about 5 seconds never heard before on boat, then sound normal again, it idles and revs fine..
