Hello: How many on here have experienced this issue, with a Yamaha setup. I have a 1992 Grady White 244 Explorer Closed Transem, I use Yamaha lube 2 stroke oil that is new and sealed not bulk! and ring free and Yamaha fuel stabilizer. Now i have owned at lest 5 other Yamaha setups and never had the problem with water in oil. Now why am i posting this is because in 2013, i had the original 225 Eng lean out on me because oil pump went therefore the pistons took a beating. So i needed to find someone who Remanfuctured Eng, I did I'm not going to name the Company, but anyway I took the boat there and they said the eng was toast do to oil pump nothing, about water in the oil on the work order. So traded it in and had them build me a 2003 300 hp 2 stroke they had at $9,000. also they recommened that i have the the oil tank removed and cleaned and replace the oil pump plus change the fuel lines form the tank back to the eng and clean the battery cables at the cost of $1,250 . So i get the boat back and following the break in period and 3 weeks later its back at the shop do to a bad head gasket or cracked blocked, they made good on that. Boat ran good throw the summer weekends with no issues, Now in Nov of 2015 I used the boat the week before with no problems. Its time to go for strippers , and that's what i wait for all year. So we get to the Boat early stat it up , head to the gas dock and head up the creek to the bay, so i go to get the boat up on plain and something didn't seem right so i back down , and re try again , this time it sounded like i throw a rod bearing . So made a call to the shop and back down it went. Never heard nothing from them in about the Eng and cause in 4 months so i made the call to them , they claim that Eng failure was do to water in oil and scored one cylinder. I find this hard to believe, that the eng let loose that morning like that with out any Pervious warning . this eng has a 3 year parts and labor warranty from Nov 2013 to Nov 2016. Now once again i'm told it's water related and there not going to warranty a water related issue. I believe i was sold a lemon from the get go. They should a least split the cost for the repairs. Remember they pulled the oil tank cleaned and replaced the oil pump, not me! So now im out $10,250 . Is this worth going to small claims court for. Thx for any input on this matter.
