I called Mercury directly today and gave them the serial #. Even they said it weights 264 lbs, not 303 lbs. All they could guess is that the 303 is with all fluids and a stainless steel prop. Said...

This motor is on a boat I want to buy and have a deposit down on. I was expecting the motor weight to be 264 lbs based on NADA guides and prior research. I asked the seller for the serial # so I...

Do these things extend the life of motor mounts ?

This is the check valve between the hose attachment(for flushing) and power head. I need to replace but find the part number. I don't need or want a "kit". Just the valve. Pic below...

Ran the boat for about 45 mins yesterday. Poppet is finally running clean and I didn't get any alarms at higher rpms. I did get a singe beep at idle while tied up. Indicates running cold and the...

Wow..having to pull the powerhead to resolve a clog in the cooling system is a more major job than I would have imagined. If it comes to that I'll have to take it to a Merc shop. Is that kind of...

Update:Opened up the thermostat and poppit. Both had lots of sand/shell..the poppit area was completely clogged. After cleaning and reinstalling both I took it for a water test. Still getting alarm...

2008 115 Optimax Serial # 1b723350

About 30 days ago I hit a sandbar and sucked up a bunch of compacted sand and shell that clogged my cooling system. I eventually got some telltale stream going...

I like that idea. I'm going to soak with acetone, heat up with a hair dryer, then go at it with a brass bore brush. I'll report back

Got the plastic strainer out with hot screwdrivers in a variety of sizes. Still need to clean the threads. I think picking at with a hot poke or knife tip will work, but tedious. Any...

1.5L 115 Optimax(2008) Serial #1B723350

How would I go about getting a large flathead screwdriver in there far enough and snug enough to unscrew?

I've been trying to resolve overheating issues that began after hitting a sandbar. I started with the water pump since it was due for it, but am still getting overheat alarm and the telltale looks...

Have an 08 115 Opti. Started with a 19 4 blade prop and it was too much. My 17 ft boat was very sluggish out of the hole. Swithched to 17 and it came alive. Hopefully you will have the same expericne.

Bump...to see if anyone else can shed some additional light on this part # ?

Thanks Joe. I won't be able to lay out and measure until the motor is apart(I don't think). I'm trying to make sure I have the correct parts ready before getting to that point. You would think this...

The savings on the parts I bought used vs new is about $400 IF THEY WORK. Well aware new bushings, seals, fasteners, gaskets etc will be needed. Can you elaborate..what would be the potential...

2008 115 Opti with a little over 1000 hours. Despite rinsing with fresh water 100% of the time and routinely spraying with CRC Ccorrosion has caused these parts to wear and now there is excessive...

That's a lot..$90 is nearly 10% of the cost of a new one. I'm only willing to spend about $225 on the repair total. I think I'll just buy a new Ipilot and if/when I find someone to work on it locally...

50"-the smaller bow mount size

I can't find anyone in the Charleston, SC are to work on this thing..hard to believe I know! Next motor will be Minn Kota simply for the fact that I can get it repaired. I wouldn't mind shipping it...

Running through a tight creek in the marsh last night and the spartina grass rubbed my hand control trolling motor, which turned it on and a rope I had on the bow cleat got wrapped in the prop. I...

I have an 08 115 Opti. The play on the prop shaft and the noise is normal. The flo torq III is much quiter than my flo torq II was

Around $300 in the Charleston area..which is why I learned to do it myself even though I'm not very mechanical
