I think I know what all to have checked before buying, but if the compression test is okay and the lower unit oil is looking ok what else should I be worried about? I am looking at a 19991 chaperrel that looks in mint condition from the pictures on the internet. The upolstery looksas if brand new but there are not any pics of the engine (115 johnson) so want to here some thoughts before the "test" drive.<br />Thanks,<br />Kojak
