What would do that to the edge of the piston? This engine ran excellent before pulling. I got it used a couple months before the season ended here in Michigan.
Last winter I upgraded my engines and one had some very bad damage. It ran excellent so I was surprised when I saw the pistons. It was a GroupK 781 and it needed a bore and pistons and the pto seals were leaking.
I’ve been using Pennzoil marine but I’m wondering if there is a better oil that...
Thanks, I’m building a Tpe964 and a Dasa 950 8mil both with 148 solas mags and I’m trying to figure out what pitch props might work best. I’m using Bpipes on both my engines.
Oem Japanese screws are “JIS” Japanese Industry Standard. They are just a little different than Phillips and can be damaged trying to use a Phillips. You can buy JIS screwdrivers and impact bits.
Ada high comp head is easy and will give a nice little bump in power. MSD enhancer is easy and give a little more pop. Look for a “FACTORY PIPE” brand B-Pipe for cheaper while you get bored and want more power. Then go big bore a couple weeks later
