I have a 5 year old Yahama 150 four stroke that is 5 years old. Has about 250 hours on it. In September I started hearing a subtle whine noise at idle. Didn't think much about it as it kind of came on gradually. Took it in to a dealer for winterization. Dealer said the engine harmonic balancer needed replacing, $600 including parts. Dealer said some of these are going bad because the gears are made of a fiber material that wears and can come apart. If the gear comes apart debris will clog the oil system causing catastrophic failure. The new balancers are made of better material and include an oiler system. Something to think of if you have one of these motors. That said I have complete confidence in this motor.

Currently just to my Facebook family and friends. I could start a topic on this fishing forum but it could be quite boring. Didn't catch a laker on 3 trips to Burntside last winter. Did have good fishing on Vermilion-Trout in the BWCA in early January but that can be very difficult travel.
Went to Mille Lacs with my dad and ended up with 17 perch and one tullipee. That was on Sunday we fished hard and I burned through 3 9 amp batteries I would say about 25 holes per battery through 32-36 inches of ice.
