The motor is a late 90’s Mercury 25hp 2 stroke. I’ve owned it three years and changed the plugs once, about 40 hours ago, best guess. It started to idle a little rough and take a little more effort to start, so I bought some new plugs. Upon removing the old plugs, I noticed that the plug from...

One of my trailer tires is beginning to check between the tread—time to replace. I’ve always used a basic bias ply tire on my small trailers. I haven’t had any problems with them, just lucky maybe? 90 percent of my driving is highway, lots of 50-100 mi days. I cruse along at 75. The boat is a...

This made in Japan motor is for sale locally. The asking price is reasonable. I’m considering buying it but have no general knowledge of mid-eighties Yamahas? So just seeing who out there might know what the overall quality of these motors were. And what the parts availability and price is...

I’m considering adding a casting / butt seat to the front deck of my 1648. What I’d like is one of those smallish partial seats on an adjustable pedestal. It would serve as a leaning post or a place to just take a little load off the feet and add enough stability to make operating the foot...

I was wondering if using my boat gas in my weed eater was a good idea? The mix ratio is the same. Sent from my iPad using Tapatalk

I live in northern climes and, in spite of my love for boating, have to store my motors for about six months of the year. I’ve had good luck with 2 stroke carb motors running them dry before storage, no plugged jets. This is my first year with an EFI motor, a 20 hp Tohatsu. I was wondering if I...

I’m in the process of giving this motor a tune up. It idles smoothly runs up good but— there is a spot between idle and full throttle where it bogs down. It’s only noticeable when the throttle is advanced slowly, then it is very apparent. I have disassembled and cleaned the carb, soaking and...

Just went through my second tachometer. The first was a Tiny Tach, the second a knock-off. My best bet is that moisture killed them both. I store them inside but boat in all weather. They both lasted about one season. So what I want to know it’s this typical of these little tachs? Is there a...

I’m considering a new outboard purchase in the 25 hp range (maybe the new Yamaha) and was wondering about power trim and tilt and river running. I do a lot of my boating on a river where shallow water and rocks are the norm. I have been using 2 strokes, a 15 and a 25, which tilt ok by hand. I...

1998 25hp 2 stroke Mercury motor cuts out at full throttle. The cut-out happens every minute or two and lasts just a fraction of a second. It does not cut out if I drop the throttle back to 3/4. My thinking was a fuel flow issue? I’m using an old OMC 6 gal gas tank. I’m not sure if the cap on...

I’m sorting things out with this, new to me, boat and motor and had a couple questions. But first I’d like to say thanks to the person who posted a question about a hard starting 96 merc and those who replied. I was confusing the primer on this motor with a choke. Now that I have that straight...

I just purchased a boat and motor from an estate sale. The motor is a 1998 Mariner. It has 15hp stickers (local hp limit issue) but when I check the serial number (the only identification I can find on the motor) it comes up 20/25 hp. How can I tell if I got a 20 or 25? I would need to know...

Looking for some advise from members with experience with this vintage of Merc 2 stroke. I found a motor on CL. It’s in mint condition, very low hrs. I’m more familiar with the OMC design. Is there any thing I need to look out for in these old Merc’s? How does the tiller-shift mechanism hold up...

This boat is on sale on CL for a what I think sounds like a good deal. What I’m looking for is some opinions as to the quality of this make and model in general. Thanks Sent from my iPhone using Tapatalk

I’m looking at a boat and motor on CL. It has a 1999 2stk Johnson that has spent its life in a small HOA pond. So most of it at trolling speed. The maintenance guy description is that it idles fine but bogs down when you give it gas. So, I’m not sure what questions I should be asking about this...

Living in northern climes, it's coming up on that time of year--storing the outboard for the winter. My old 15 hp OMC 2 stroke, I'd just run the carb dry and store it inside upright, fresh lower unit lube, and start with fresh gas next season. It worked well. I picked up a 2008 20 hp Tohatsu 4...

I wanted to share a couple things I learned from selecting a new prop for my 1984 15 hp Johnson. First, the 200 rpm per pitch size was not even close in my case. And it makes sense if you do the math. The standard prop being a 10. One size up or down is +or- 10%. Also in case of a two stroke, if...

Broke the shaft on my Minn Kota enduramax 55. Does the broken shaft allow water in the lower part of the motor? Does it need to be dissembled and dried? Or can I screw in a new shaft and run it? Thanks Sent from my iPad using Tapatalk

This is my first boat and motor. I've already learned much from this forum, thanks. My boat is a 1436 Lowe Jon. The motor is a 1984 15 hp Johnson. I use it for river fishing primarily. With a friend and trolling motor and battery my weight is at about the max for this boat--610#. Also I added a...

I recently purchased a 1984 15 hp Johnson. The motor was in excellent overall condition but I was uncertain of the condition of the water pump/impeller so I made replacing it one of my first projects. All went smooth except for the little O-ring that goes on the top of the shaft, a couple inches...
