I have a 2 part question<br />recently purchased a boat with the above engine. I went to change the plugs and the gap was very tight .20<br />Can anyone tell me what the proper gap size should be.<br />If it is not .20 what would be the reason/effects for running a engine with that type of gap.<br />Thank you in advance

Your plug should be a Champion QL78YC gapped at .030".

Sometimes you will get a poorer quality idle with a very close gap.
