Maybe I'm being foolish (again) but I'm looking at a boat with a '97 Suzuki 115 on it. I haven't seen it yet but the boat looks to be in great shape at a great price. The owner says that the engine starts and runs OK, but there is no spark at the top cylinder. I'm thinking coil ($40.00) or at the worst a new power pack ($200.00-300.00). Any thoughts on what else it might be? I hate to get tied up with another project, but...
