Does anyone know the part number for a 2007 115HP EFI 4 stroke ECM and a good source to buy? All the parts diagrams have these two options
Mercury ECM, Engine Control Module - 115
Part# 89772721T
and
Mercury ECM, Engine Control Module - 115 EU
Part# 89772724T
Which one?? :facepalm:
I have a '08 Merc 4 stroke that has a air filter/silencer and the foam has deteriorated on the filter. I did a search on the net and discovered this is a problem with the new 75-115 motors and they seem to fall apart after just 25-50 hours. What's the solution. These filters cost anywhere...
OK, I removed my old bilge pump to install an automatic bilge. Confirmed that the new pump is working by jumping it to a battery, float and manual override works fine. Install the pump and put the switch to auto and the pump starts to run. Put the switch to off and it stops. Put the switch...
I have a '08 Merc 75 EFI and noticed it uses a restrictor plate under the air filter. Is there any issue with removing it. I'm not trying to make a 75 into a 90 just noticed that it was a huge restriction and thought I would remove it for some added performance benefits. Really only want to...
Can I just change the steering box (helm) and use the existing cable to give me no- feedback steering? How do I know which box to buy? The boats a 08 Princecraft 164 with a 75 Merc.
Thanks
This is a new to me '08 Honda 40 4 stroke with remote. I purchased the motor just before winter to put on my pontoon boat. I purchased the motor from a marine dealer in MN which is about 200 miles from me. The motor did come with a 50/50 warranty. I installed the motor on my pontoon and...
I just installed a new 2006 Merc 60hp on my G3 V170T to replace the Yamaha 40hp 2 stroke. I'm very happy with the motor but just wondering in Merc offers an optional longer tiller handle? I find myself having to reach further back then the Yamaha.
This is a continuation of a previous post. The motor is a '04 Yamaha 40hp 2 stroke which I bought this spring. It has around 30-40 hours on it . This is the idle after I have done the following which didn't really seam to help much. I replace the spark plugs with NGK's, all the carbs were...
I have a 2004 40hp Yamaha that's new to me this year. I bought it earlier this year and the motor has maybe 30-40 hours on it. Ever since I've owed it the motor has a "lumpy" idle. At up to around 1500 it idles rough but after that start to smooth out and runs fine. I can troll with it at...
The motor is a 2004 Yamaha 40tlrc that has about 15 hours of use. If you listen carefully you can hear a rattle noise as soon as it put into gear (forward or reverse) and as soon as you get off idle the rattle stops. It doesn't rattle in neutral. Noise seems to be coming in the area between...
I just purchase a 2004 Yamaha 40TLRC that is like new. It has about 15 hours of use on it. Today after mounting it to my boat I started it up in the yard with the ear muffs on to run some Seafoam through it and notice at idle and in gear a rattle noise which seams to come from between the...
I got a good line on a 40hp used maybe 30 hours but has console steering and I need a tiller for my fishing boat. I found a complete tiller on Ebay for a year 2000 40hp Yamaha 2 storke. Will this fit the 2004? Also does the 40 tiller use a friction lever? Would there be a friction bolt on a...
The 2004 50hp Merc 4 stroke that I've bought has a slight bend in the shaft after the seal. It's about .001 to .002 out (a guess, I haven't measured it yet). Is this going to be a problem? Previous owner said they never noticed any vibration. Local shop said they could straighten it for $300.
Ok, I have a '98 Princecraft 14.5" boat with a beam of 73" and transom measures 70.5". Picture is an example.
The transom measure 20". The boat weight from the manufactures website is 520lbs. The boat has a full floor with livewell in front and Minkota trolling motor with battery mounted...
