...This is in regards to my 1971 Mercury 1150 (115 HP) outboard.
Problem: When I advance the throttle to wide open it will sputter and pop as well as only reaching 3200 RPM.
...If I back the throttle off of wide open a touch it will stop sputtering/popping and slowly climb to 3800-4000 RPM...
...I decided to try the prop wizard, for getting me in the right range for a new prop.
This prop is for a 1971 1150 Mercury (115 hp) fitted on a 19' Marquis closed bow. The hull is a semi-v. This motor has never ran on this boat before. There are no trim tabs, or PTT. I should be hitting...
Hi again folks,
This is in regards to a 71' 1150 (115 hp) Merc.
I am trying to troubleshoot an ignition problem and I am on the coil atm. I am doing a simple ohms test.
1. "pos" and "neg" lead wire on the Rx1 scale = 0 (which is correct)
2. Either of the primary leads and coil tower on the...
...Ok this may seem a bit odd but here goes.
I hitched up the boat today to take her down to the gas station to fill er 'up. Before I left the house I added a quart of 2 cycle oil, enough of oil added with 12 gallons of gas to make a 50:1 ratio. That was O.K
I made it down to the gas station...
(I hope this is in the right forum)

Hello yet again :)
This is in regards to a 1971 1150 (115 hp) Mercury outboard. On a 19' closed bow with a 17" pitch prop (3 blade).
When I ran the boat in the lake a few weeks ago it would only reach 3000 rpm at WOT. So I decided to do a link and sync. I finished that today, primary pickup...
This is for a 1971 1150 (115 hp) mercury.
Ok, I am a bit confused here. My motor does not have a timing pointer installed, and from what I understand that year did not come with a separate pointer, they were scribed into the cowl support around the flywheel. And my mark is gone on the cowl...
I went to adjust my timing the other day on my 71' 1150 (115 hp) merc.
After I pulled the cowlings off and the top cover I noticed no timing pointer? There is a tape on the flywheel with the timing mark but no pointer that stands out at me?
I did see what looks like a pin hole on the...
Well I put the boat in the water today for about 30 minutes. After I got back home with the boat on the trailer I remember to pull the drain plug, when I pulled it, a few cups of water came out. Is that a normal amount of water to be draining out of there?
It has been through a pretty heavy...
This is a 1971 mercury 1150 (115 hp)
Well I changed the water pump, everything went ok except trying to get the intake tube to seat into the waterpump housing.
I put the boat on the lake today and come to find out I have no reverse gear. When I try to shift into reverse it just grinds? What...
Greetings,
I also posted this in the electrics forum, I am not sure where to post:confused:

Greetings,
I am in need of a bit of help..I am in the process of identifying wires/rewiring on the boat. The owner before me seems to have a bit of a mess here with wires. I am onto the tach wires and trying to figure these out. I have attached photos. This is for a 1971 115 hp inline...
I am going to be fine tuning the carbs up and I was wondering when I adjust the idle mixture do I adjust one carb at a time or turn the three of them equal distances and wait for the results? thanks in advance for the help.
I just picked up a boat/motor combo with a 1971 115 hp merc tower of power.
I want to change the gear lube...I do not have a manual for it, and the only brand motors I have ran are johnny/rudes.
What brand/weight should I use? Thanks in advance.
Can anyone comment on the 1971 115 hp Merc O/B? I am looking at a boat/motor/trailer package with this motor on it.
He says the motor has 140 compression in all of the cylinders. But it has a hard time starting cold. After the first start it is easy to start.
Comments/opinions please?
