2017 Yamaha 150XB. 350 hours all salt water. Boat kept in water 6 months/year. 17 Parker 21SE.
Exhaust guide corrosion. Dry exhaust can not flush. Tried to JB Weld (Xtreme Heat) to get me through the season. No go.
Estimates were $3-3.5k dependent upon what other issues might be uncovered. Bought a used hoist and $900 in OEM parts and service manual.
No corrosion on the adjoining powerhead or oil pan. Yamaha leans towards over-propping or long periods of trolling. I can hit rev-limiter if trimmed excessively and have rarely trolled for fish. The consensus amongst the afflicted is poor metallurgy on the guide. Plausible as the connected components, seperated by a thin metal gasket were not affected.
Pro's say 12-15 hours. I'm estimating 30+ for me. A lot of one step forward two steps back. I found the only useful info in the manual were torque specs. Ofttimes the parts diagrams on the web were more helpful. Back in the water and have about 25 hours on the repair. Aligning the powerhead was, probably, the most challenging part as I was without a helping hand.
