Yes, its 50:1. If this motor is new to you, you need to perform some maintanance. I own the exact motor and with some TLC it has basically given me trouble free operation for the past 4 years.<br /><br />If you need help send me an e-mail to vze2mfqx@verizon.net<br /><br />After using the correct oil/gas mix you need to to a decarb and after that swap the plugs out. Also, change the lower unit oil. (THIS IS TRICKY) on this model. The drain plug is a very small allen wrench fitting on the front of the lower unit. If it doesn't come off e-mail me and I will tell you how to get it out.<br /><br />Use GOOD oil. I like Quicksilver Premium Plus 2 cycle.

Hey FTB I just bought a boat with the same motor but an 89 and I have 2 issues with it you might be able to help me with. It is hard to get going. Stalls allot. It has new plugs and stators. The other thing is the motor slowly sinks down. Is there a hydraulic adjustment.
Thanks Rick
