Hi,
I am considering buying a boat with an 80's era 2-stroke 75 hp Suzuki, but am concerned about low compression ratios on one cylinder: #1 = 128, #2 = 138 and #3 = 140.
I spoke to a mechanic about this and he told me that a likely cause may be an overly rich oil mixture. As it turns out, the seller was running a double rich mixture because he was concerned about his oil pump giving out, so he pre-mixed his fuel as well.
I'd like to know if anyone has any thoughts on this before committing to a purchase? Perhaps I should have a second test done while the engine is running on a leaner mixture?
Thanks.
