    Yamaha 55hp EL (Mariner) difficult to get out of drive

    Hi I have a 1982 Mariner (Yamaha) 55 EL outboard. On the water today I was struggling to get it out of drive and back in to neutral. Reverse to neutral seems OK but trying to taking it out of drive is a real struggle and feels like I am going to break something if I keep forcing it. When the...

    Brand New Starter Motor Won't Work!

    Hi, I have a 1982 Yamaha 55hp EL outboard (labelled Mariner but essentially the Jap Yamaha version). The starter motor packed in so I bought a brand new one, wired it up and fitted it last week. I tested the engine on the drive way and all was great, starting like a dream. I got it on the...

    Mariner (Yam) 55 EL (1987) Gear Connection Problems

    I have a problem with the above engine. I am trying to connect my controls. The throttle control connects no problem. However the gear cable with clevis on doesn't reach the pin it needs to when the engine is neutral and the controls are in neutral. I have adjusted the cable as much as I can...

    Adjusting the Idle Speed on Mariner 55hp

    Hi, I have an 1987 mariner 55el outboard. It starts with a bit of throttle but when this is released it just dies. Is there a way I can easily adjust the idle speed so that it runs on without throttle. Thanks

    Mariner (yamaha) 55 el (1987)

    My Mariner 55 EL was working fine yesterday. Today I started it and the water is no longer shooting out of the tell tale. Its more like dribbling. There is also a lot of water coming out of the gear linkage hole/gap. I don't recall seeing this before but maybe its because I'm looking more. I...

    Hi, I've just bought a Mariner 55El 1987 (pretty much a yamaha so I've been told). Its on a stand in my yard so I obviously want to test it to get it running. I connected the battery - to the large bolt on top near the flywheel. On the solenoid, there was already a wire coming from the bolt...

    Suzuki DT40 cutting power after a short time

    Hi I have a DT40 (1970s). On the last 2 occasions that I have taken it out, after a short burst of full throttle, the engine dies to a very low speed. It will maintain this speed for a couple of minutes and then normal service will resume for another couple of minutes and then it will die...

    Suzuki DT40oil light flickering and cutting power

    Hi I have a 1970's DT40. I've been out in the sea 5 times now and the last couple of times the engine has felt a bit ropey. Today it started OK but sounded as if it were idling a bit low. I engaged the gear and went off to sea. As I accelerated slowly after leaving the harbour the engine...

    Universal Fuel Filter

    I have a 1976 Suzuki DT40 outboard. Recently, when pumping the fuel bulb I have noticed some fuel escaping from the top of the fuel filter. On closer inspection I realised there was no o-ring installed in the cup. I tried making my own one and buying one from a local hardware shop but they...

    Splicing a HT lead!

    So I was checking my spark plugs today and I noticed that one of my HT leads on my DT40 felt a little limp. It must have had a hard life as its been repaired before and has a sort of splint midway with cable ties round it. Anyway, it felt limp due to a split in the original insulation and the...

    Suzuk DT40C won't start

    Hi, I am new to boating and outboards but learning very fast. I have bought an old Suzuki DT40C circa 1985 outboard. I looks in very good condition. It sat for a while as I didn't have the correct fuel socket. I started it for the first time the other day and it ran OK for about a minutes...
