Headhunter Posted October 28, 2017 Report Share Posted October 28, 2017 After almost 2 months of working on the house with no boating and no fishing I couldn't stand it anymore and jumped in the Maverick for a ride. The F70 cranked right up and fired but belched oily smoke for about 2 minutes. It cleared up after that and ran fine but can anyone tell me why it happened? The boat has been on its lift since Irma with the motor in the down position. I tried the Pathfinder after that and it started and ran fine right out of the shoot, no smoke. The pathfinder has a 200 sho. Thanks in advance for the expert advice. Link to comment Share on other sites More sharing options...
Captbill296 Posted October 29, 2017 Report Share Posted October 29, 2017 A Yamaha mechanic told me one time to keep the motor tilted slightly so the oil drains properly back into the sump. All the way down is not recommended. Ask your mechanic to give you his opinion. Link to comment Share on other sites More sharing options...
polliwog Posted October 29, 2017 Report Share Posted October 29, 2017 Haven't heard that suggestion before. I keep on motor all the way up with a boat in a slip and my maverick 40 HP yama all the way down . The HPX stays in the garage all summer in the down position and when I start it up after 6 mos runs just fine after burning off the fogging oil.
