Can someone tell me what type spark plug I need for a 2000 Johnson 225HO (don't have the model number with me)? It's started the last few trips out becoming increasingly hard to get it started when getting it off the trailer. After the initial start of the day, it's fine. I normally fish at least one tournament per month if not two so it doesn't really stay parked that much. At first I thought I was just flooding it out by pumping up the bulb too much but it doesn't matter what you do, it's going to take a while to get it to fire off first thing. Temperature doesn't seem to matter either, it did it before it started getting colder. Once it's started, runs smooth and no problems.

Thanks!
