Oil Change
I have an F250 on my 228. The 10 hr. cost me $360 at the yamaha dealer down the street. The 100 hr. cost $620 and the 200 hr. was gonna cost over $850. They charge $110 an hour. For the 200 hr. I told them to just do the oil change and the required inspections. They changed the lower unit oil too (by mistake they said) and the bill was $307.
These guys changed the plugs and thermostats at every check up and were gonna change the water pump too at the 200 hr. They also changed the zincs and the trim tab zinc was missing (ie: fell off) when I pulled it out of the water for the 200. I can change plugs, zincs, the thermostats, and the water pump myself and use the $110 an hour I save to buy gas.
Cheers,
Dan
