I just inherited a mercury thunderbolt and I do not know what the year model is or how to take the water pump out the serial number for the motor is 3183142. It is a 9.8 I believe. I would greatly appreciate any information.<br /><br />Janis

Re: Mercury Thunderbolt help

Welcome to iboats.<br /><br />You might try your public library for a service manual. Many of them have manuals. I can't give you a specific year, but that would be somewhere in the mid 60s. The water pump is on top of the gearcase. You have to remove the gearcase to get at it. Just two nuts hold it on, one in the front and one above the prop under the plate. Getting it back on is a real cusser.
