Hi, sorry to hear you did not like your 150HP and I wish you well with your new outboard, but we have plenty of E-TEC that run in salt water that at the 3 year service the leg bolts are fine, but you are missing the point, if you want to service an E-TEC every 6 months that is upto you, but you do not have to to get warranty and the fact it less than 5% of E-TEC will do anything like 300 hours in 3 years.
Cheers,
Huey.
