I HAVE A 1977 MFG fiberglass trihull 15' fishing boat.
Boat is rated to handle 85hp max
625 lb people max with1225 lb max with engine and gear.
I have a 1982 50hp Mercury 2 stroke with 10 ⅛" x 13p aluminum prop.
With 2 people weighing total of 375lb, top speed is 27 mph. Same top speed with...
I have a 1972 Johnson 9.5 HP. I would like a little more power. I found some one that wants to trade me a 15 HP Sea King. Everything that I have found tells me that it is a Chrysler.
Is the Sea King a good motor? Are parts readily available and afforrdable?

The 1981 70 HP Johnson runs great! Ran it in tank . Forward and reverse. I noticed water coming out where the foot meets the "midsection". Water in oil. I pulled 5 bolts out . The foot is not coming out. How big of a hammer should I use to get it off.

I am getting NO spark from any coil. I do not have the fancy tester. I am using an induction timing light to test for spark. I will search the forum, as well.
This is on the parts/replacement motor that I bought to replace/repair the previous engine that I posted about previously...
I did just that, but the one bolt that broke off ( center right) broke off at the head of bolt. As seen in picture the head will rotate counterclockwise with the remainder of bolt frozen in head, but rotating in block. I tried heat and tapping with a lot of blaster, but no luck. I will try a...
The head gasket appears to have been replaced (left finger in picture). The head cover gasket (right finger in picture) is original. Is it possible for head cover gasket to cause low compression on 2 adjacent cylinders? Or a better question could be what typically causes adjacent cylinders to...
This starter mount is broken. Would JB weld be my best option. The cause of this is due to the top front bolt backing out, putting too much pressure on this mount.
Yes. Bypassed, and using newer push to choke switch.
There seems to be nothing to keep choke open. When I manually set it in open position, it does stay open. But when power is disconnected from solenoid, it stays in choke position. Gravity only is keeping in place. Take a look at picture...
Choke solenoid activates properly when power is applied through switch. When switch is released, choke stays on. What is required to release choke? There is no "spring" resistance when manually operating plunger.
Thanks,

Also thank you to those that replied to previous posts. I now know...
Here's a picture of my choke solenoid.
This is a 74-75 engine with a newer push to choke switch, using the purple/white wire, eliminating the temperature sensor for now.
