1989 Merc 9.9 2 stroke yes still have the carcass.Bought a 1992 9.9 mariner which ran great at idle but currently apart due to vertical play in the rod bearings.Hoping to get that back in order and I will be selling the 4 stroke.Too heavy for a 78 year old.
I was going to close an eye on the excessive weight but
A......To fast for trolling at minimum throttle.
B......Caused my entire 12 ft aluminum boat to vibrate including the rods simulating constant strikes
HELP pleaae
2025 EFI 9.9 MERC Low usage
Hello folks
I am trying to determine whether I am being overcharged.
Question..... how long does it take to remove a blown powerhead and replace it with a rebuilt powerhead on a 9.9 2 stroke Mercury approximately 1990 model.
Thank you
No you do not need to take the bottom plug out.
You run the motor in a barrel for 5 minutes or so , And if there is any water in there the entire oil will be milky top to bottom. Then take out the top breather screw only and take a thin piece of wire bend it at right angles and work it in...
Just to put things in proper perspective. I did not specifically complain about $30 a litre but when Amazon tries to suck me in for $61 a litre a post on here is warranted.
"Clear Silicone is not an RTV product"
If R TV stands for room temperature vulcanisation as you State then I would think it is an R TV product. It vulcanizes beautifully at room temperature.
I wish I lived where you live because around here. The only stuff that is marine approved or marked marine is either quicksilver or Royal purple. All the others say nothing about marine other than 80/90 weight But do say high performance.🤔
