Hello, i am new to this message board and i am hoping you can help. I have a Mercury 90 hp 3 cyl i believe a 1996 model serial number is 0D237890<br />I Have a few question so bear with me.<br />#1. i need a lower unit, which years and HP will fit my outboard?<br />#2. i removed the oil injection ( i know it works but i am from the old school if the oil is in the gas then i "know" my engine is getting lubricated) so my question is to turn off the low oil alarm do i just connect the two blue wires that did go to the low oil sensor together?<br />#3. What can be done to acheive more horsepower, meaning is the 90 and 115 basically the same engine? If so what would have to be changed? I am not looking for a racing engine, but if i can make my 90 into a 115 or something like that pretty easy with just carbs and exhaust tube swap then i am game.<br />Well, i will stop here, i am sure more questions will pop up. Thank you for your help and happy boating.
