sleepydragon Posted May 12, 2015 Share Posted May 12, 2015 Hi Raiders, I am on the market for repower my outboard. I have found and Yamaha F70A 2011 model advertise for cheap price. The problem is this motor has 4900Hrs between 0-1000rpm according to the report from the dealer. I am not sure if it is worth to give a go? Please help Cheers Link to comment Share on other sites More sharing options...

brad_tate Posted May 12, 2015 Share Posted May 12, 2015 That is a lot of hours on the motor. I had a Yammy 60 for 6 years from new (09) and would have definitely have put less than 1000 hrs on it as a recreational user. I don't understand the 0-1000 rpm report however. On my 5m tinny I planed at 3400 rpm and trolled well over 1000. That motor will open out to 6k and it's sweet spot will be around 4k.

Jewhunter Posted May 12, 2015 Share Posted May 12, 2015 Those hours are simply idling hours. A lot of guys drift fishing offshore leave their engine running all day, rather than stop & start it. My neighbour does it. It is a lot of hours for a 3-4 year old motor though. As Tef said get it checked out by a good mechanic. Link to comment Share on other sites More sharing options...
sleepydragon Posted May 13, 2015 Author Share Posted May 13, 2015 I think that what exactly Jew said. They left the engine on while drifting (I do it as well) . Just wonder if it does any bad to the parts of engine. Link to comment Share on other sites More sharing options...
Guest no one Posted May 13, 2015 Share Posted May 13, 2015 204 days at idle for a 4 yr old motor, 15% if it's life it's been turned on and idle? Something is wrong with this! It means it's idled for 3 1/2 hours a day everyday for 4 years solid! Link to comment Share on other sites More sharing options...
Guest Posted May 13, 2015 Share Posted May 13, 2015 I could have just been left in the water with the prop turning in the current if that is possible Link to comment Share on other sites More sharing options...

mike2153 Posted May 13, 2015 Share Posted May 13, 2015 It's a commerical engine for sure, the boat it was on was properly never pulled from the water meaning the engine has never been flushed. Would have a very poor service history. I wouldn't buy it, in fact I wouldn't put it on my Boat if you paid me. If in doubt with these sorts of things don't but it. Plain and simple.

Thanks a lot of Mike. I think the same too. Look like its a commercial engine. Link to comment Share on other sites More sharing options...
