Very interesting. This is actually a Yamaha built mariner, so kinda confusing. I'll look more on the block for an anode but I'm not aware of any. I do flush it when I use it in salt water, but I mostly use it in fresh water. The previous owner clearly used it in saltwater, that motor lived in...
Hey y'all,
I took the head cover off my 5hp mariner (this model has no head, just a plate covering the water jacket over the head) to check for sand and salt buildup and clean a bit. I noticed some deep pitting eating it's way towards the outside of the power head (on the outside wall, not the...
Thanks! I just really didn't want to drill any holes if I wasn't confident it would work. I've seen a few no drill versions but they are both expensive, and not made for small outboards.
Thanks! I'll very likely trim the front back so long as it doesn't affect the structural integrity. I forgot to mention, it's a two piece design molded to the motor foot, so I don't have to drill any holes in my ventilation plate. I'll take pics of that later. I'll definitely trim some of it...
That is very similar. Yeah I do have quite a bit of mine close to the transom. I left a lot of glass so I could trim it back later if I needed to. Easier to remove fiberglass than to add it back. I might trim it back a bit, but I've also seen other plates with almost as much plate forward of the...
Here's a test fit after modifying it. I'll probably trim back the edges and vertical fins a bit for less drag. I think the downward fins are only necessary to add rigidity to the glass and funnel water around the prop.
Update after lots of farting around. Adding weight forward helps a lot, but I recently made a no-drill compression plate for my 5 hp. Boat has much better hole shot, and I don't need to shift my weight much to get out of the hole. Needs a little adjustment still, I had to raise my motor 2...
