I hope this is the last time I have to ask for help , but I have been working on my force 50hp<br />and narrowed my problem down to the cd ignition.. now my problem starts ..after <br />looking on a few websites to order a new unit I thought I had the part #....116-3301..<br />that seemed to match up with my model # ..then I came across a few sites that listed <br />part# 166-8301 that covered all 50hp motors for that year. im not so sure what one to get now .<br />it is a 98 50hp ..model 507x9b serial# 2728. any help??
