[walks84]

Gday guys I know nothign about motors, I was recently giving a savage boat with an 85 horsepower Johnson on the back its either 86,88 model. I strted when I fitrst got it but as Ive been away for a failry long while I tried starting it the other day and it wont even kick over, I've been told it may be spark plugs.......any advice would be much appreciated

Have you checked to see if you have spark to the cylinders, spark needs to jump a 7/16" air gap and be bright blue.

After you verify spark by pulling one plug at a time, touching the plug to the block, and cranking it over, you should check out the fuel system. Make sure fuel is getting to the carb by checking the float bowl. If you've got fuel and spark, you will probably want to rebuild the carb. Also make sure it pumps water to prevent overheating.

Checking spark by touching the plug to the block will not give you an accurate results. The spark needs to jump a 7/16" air gap to fire properly under compression.
