Last week I changed the engine oil and filter, put new end caps & pencil zinc in the Sendure heat exchanger and replaced the raw water impeller. The bottom of the raw water strainer fell out when cleaning so I got a new one.

Yesterday with the help of my son Alex we replaced the three tiller bolts. Two of three bolt heads broke off during removal. They are 5/16 X 3 1/4 bolts. We could only buy 5/16 X 3 1/2 bolts from Ace Hardware. West & Home Depot don't carry bolts longer than 3 inches.
