Measure from the cavitation plate (the one above the prop) to the u bend where the motor hangs on the transom. They are usually considered 15", 20", 25".

    Not enough info. Looking at 1998 models, the serial does not come up. There are also multiple models in the 25 HP line for that year. Sorry. If you cannot see and hear the motor run, I would steer clear.

SOURCE: mercury outboard 60 motor turning over but not firing up.

get some starting fluid and spray a liberal amount into the air intake, then try to turn over. if it will not turn over with starting fluid you have a problem either with your ignition system, example: plugs, coils, wires, ect. If it does fire and then die out with a shot of starting fluid then you have a carb problem. If the boat has been sitting anything over a month thats where I'm betting the problem is. Post back after you find out if its a fuel, or fire issue and we'll start the repair process.

SOURCE: I have a 2009 40hp 4 stroke outboard. It sounds

not enough info. what Manufacturers and model? is it out of warranty? here are some troubleshooting tools and procedures since labor rates at your local dealer could be up to $100.00 per hour. before you start I have two Goals for you. (1) If you learn everything you can about your engine you will become more confortable and enjoy it more. (2)confirm that your engine is ok now. is the noise your hearing piston related, or is it ignition missfire. the compression check and the ignition output test will help answer that. Tools(1) A compression gauge (2) a spark gap tester.(3) A Clymer service manual for your engine. (you can purchase from your local dealer). I know all these are expensive but if your going to be a outboard owner you will always need them. Troubleshooting (1) check compression. without the Manufacturer I'm giving you a average numbers. Look at your Clymer manual for specifics. all cylinders need to be over 100 lbs and equal each other within 5 lbs.(2) check spark output. use a spark gap tester. all cylinders should jump a half inch gap. If all these test prove that the basic operation of the engine are within specification, then we can turn to fuel delivery. unfortunately you didn't give the Manufacturer so I can't give you the troubleshoot procedures for the fuel delivery system. you will need to refer to the manuel. please get Clymer manuel you will apreciate it

Prop shaft. You have to remove the bearing housing cap. reference number 70. Remove the bearing housing. reference number 60. The bearing housing will need to be pulled out buy using a puller. If it was in salt water it can be difficult. Pull the prop shaft and clutch dog assembly.

Could be the drive shaft, or maybe your propeller.
