Problems with I/O Mercruiser Alpha One

8 posts in this topic

I have a I/O 135hp Mercruiser Alpha One engine on a 17ft Maxum boat, and today the boat won't start. For some reason the boat will not start and when it starts it won't run at idle speed. It almost seems like it's a fuel problem but the fuel gage says that I still have half a tank left. I am not very good at trouble shooting so any help would be apreciated.

Perhaps you have some water in your fuel. That could very well cause the symptoms you are seeing. With the swing in temps lately, you could have had considerable condensation form in your fuel tank.

Try putting some seafoam treatment in the tank, or just flat out drain the old fuel and starting with some good fresh gas.

Go buy a bottle of isopropanol (HEET) and pour that in. It'll get rid of any water in the tank and fuel lines.

Thanks guys, I'm going to give it a try and see what happens.

I have added some ISO HEET but the engine is still doing the same thing. I have however notice that when I prop the top plate on the caburetor open the engine runs and idles just fine. Has anyone experienced this before?

The top plate is your choke, if motor is cold it should be close or partially closed, when warm it should be completely open. You might have a sticky choke body or similar.

My first thought was the choke. It might have operated fine in the warmer temps but with the cold your choke adjustment isn't tweaked quite right or its dirty.

First thing you should do is clean the outside of the carb linkage with a carb cleaner. It that doesn't work then go onto adjusting the choke. Don't know if you have an electronic choke or one that uses bi metal springs.

You can take you a manual from your library, it'll have specific instructions on choke adjustment.

Thanks guys, I found some additional information for the carburetor and will try tweaking a few things. Hopefully that helps.

      Looking for advice on keeping the dog focused and quiet in the duck boat.  Was out today and we shot enough ducks to keep her busy, however my dog is such a hyper hypo that it's a  little annoying.  Either whining or jumping back and forth from the front and back of the boat.  Do I just need to establish the expectation and keep on her till she finally gets it or is this how some dogs are in the boat? This is her 4th year duck hunting and she has continued to improve each season.  Overall I am happy with her work, especially with the limited amount of hunting I do.  We were out today for 3 hours, shot 8 birds and she did great on the retrieving end and is pretty much focused on the skies, but if something is not constantly dropping from them I feel like I have a screaming baby on my hands.  It's not really that bad, just very annoying.   I would just like her to sit in her spot, stare at the skies and wait for my command.  Is this to much to ask?

      she's getting big

      She's up to 38 pounds at a few days short of 5 months and does not stop going 100 mph. She got exposed to a lot of feathers this weekend at duck camp. She retrieved dead ducks and geese in the yard after our hunts. The goose was a bit big so I chopped a wing off and worked with that after she picked it up and barely made it back a short distance to me.

      Fishing Report from Flag Island Resort Lake of the Woods, Northwest Angle 9/25/16

       

      Happy Fall!

       

      On the Minnesota side fishing has been great around Soldier’s and Mergan’s Point. Most points have been producing fish as well as bays due to shiners moving into the bays. Raps and spinners have been successful as well as 3/8 ounce jigs with the jig bite turning back on. Shiners, crawlers and fatheads have all been attracting the fish. The magic depth has been between 8 and 18 feet. The duck and goose opener has been successful with many resident birds still around we have not seen any signs of northern birds in the area. There have been many Woodducks and Mallards around.

       

      Over on the Ontario side the Walleye bite has been great and the Crappies are picking up. Anglers have been targeting fall spots and jigging in 18-28 feet of water. Emerald shiners are on the move to spawn so watch for them in channels and bays with creeks. The water temp is cooling down and is approximately at 62 degrees. Trolling for Muskies in 10-18 feet has also been good.

       

      The leaves are starting to change colors and there is definitely a chill in the air but, there is still plenty of time to get in on some wonderful fall fishing. The best part about fall fishing is some of the great wildlife you get to see out and about. Also, it is a good time to start thinking about your winter ice fishing trip, we would love to have you as our guest!

       

      Until next week, good luck fishing!

      First time up in Brainerd in 3 years. Went to big trout on Friday, thinking it would be a guarantee (which it usually is). Nope! Not even the rock bass were hitting! Only ended up with a couple pike and a couple largemouths. The inspector at the boat launch was showing me some pics of a couple lake trout this one guy had caught a few days earlier, a 34 and 36 incher! Saturday we were going to fish gull, but it was jam packed with people! Was there a tournament going on? Ended up at a secret little lake where my wife caught bass and pike one right after the other, while I couldn't get a bite to save my life! Was good to be back up there after a 3 year absence. Hopefully I'll find the time to get up there again.

      Very nice walleye no matter how the picture came out! Do not see many of those each year!

      We ended up keeping 9 walleyes and releasing 3 slot fish between 19" and 23".

      Here's the proof of the 28" I told you about today cliff. Unfortunately this picture doesn't make this fish out to be nearly as impressive as she was in person. I'm gonna need to work on my selfie skills.
