    25hp Mariner Heavy Steering

    Hi There. Although I don't know the model number (and therefore age) of this engine i know it is the same as this 25hp two stroke http://www.marinepower.com/products/single/2006$$$EN-$-MA$2S$F250-2_5$MA2S_25 <br /><br />The boat is nearly impossible to turn at speed and i've been investigating...

    Mariner 25 Motor Mounts

    I've read the topic "25XD pulls to one side" and it seems I have the exact same problem. Can you please tell me more about the said mounts, where they are and how to get to them? Thanks very much

    Extremely heavy steering at speed

    Hi there, the motor is a 25hp Mariner two stroke and the boat is a FunYak450 (not mine, sailing club's). The steering is cable, not hydraulic. It steers fine at non planing speeds, absolutely normal, but as soon as it starts getting up the steering becomes ridiculous - it takes two hands just to...

    WOT RPMs and HP

    I've recently had a look at the trim (it's manual) on our two motors and, following the advice found here, the A-V plates are parallel with the water when we're planing. Because I've tilted the motors out we need more weight in the bow, that sound right?<br /><br />I've also heard here that if...

    Play in gear cable

    Should I be able to move the end of the cable (the black bit with the linkage to the motor shift arm) without it moving the cable, or should it be rock solid (which seems to make sense to me!)?<br /><br />Cheers

    Would a richer fuel mix effect fuel consumption?

    Question's in the title really! We've changed (on JB's recommendation) to running 50:1 rather than the 80s published 100:1, would this cause the motors to consume more fuel from the same usage? Cheers

    1978 25hp Johnson ventilating

    Hi guys, What I'm finding, especially in a few waves is that, when up on the plane, the revs rise and the prop stops biting. From reading other posts I reckon that's ventilation The model number is 25BA78C. It's on the back of a Dell Quay Dory 13 which I'm pretty sure has a long shaft transom...

    1985 30hp Evinrude fuel consumption

    As I've said before, both my boats are rescue boats. We spend most of our time at idle with the occasional blast at WOT. I seem to be forever filling up cans of petrol to use, my estimate is that in two hours of duty we burn about 7 Litres (1.85 US Gallons, for us Brits that's a hell of a lot...

    Gear shift problem

    Hi guys, me again, with my 30hp 1985 Evinrude. You may remember i've spoken before about a hard to find neutral, things seem to have deteriorated since last time. If I disconnect the shift rod and shift using the arm, it's ridiculously easy to go flying straight through neutral, which I'm sure...

    Kill Switch

    First things first, BE30BALCO and 25BA78C. I brought the kill switches home last weekend to clean them up, now they're clean I tested them. Could you please explain how they work? It has four pins, when the button is in (lanyard on/motor on) contact is made between a pair of opposite terminals...

    Prop Sizes

    Hulls: Dell Quay 13' Dorys<br /><br />Use: Safety/Rescue, normally two up but are sometimes used to carry up to 7/8<br /><br />Motor 1: 1985 'Rude 30hp<br /><br />Motor 2: 1978 Johnson 25hp<br /><br />I've seen recommendations for a 10x13 on the 30 and a 9x10 on the 25. Are these right for our...

    Control for 1985 Evinrude 30hp (BE30BALCO)

    You may remember me posting a while ago regarding a hard-to-find neutral. I did as instructed, disconnected the shift rod and shifted using the handle. Engagement was more definite but it was still easy to shift through neutral. I've realigned the shift rod and feel on the control is a little...

    Powerboat Survey

    At my sailing school we have two rescue boats, both Dell Quay Dory 13's, one with a 30hp 'rude and the other with a 25hp johnson seahorse.We've chosen to survey our entire fleet and i've been tasked with drawing up all the forms. Is there anything I should include?(i've made the form already, i...

    Smokey Exhaust (Evinrude 30hp)

    Another problem for you to ponder...!The 'rude 30 (which, despite all its problems cold starts surprisingly well)produces a very smokey exhaust at the start of a day of operating, it may not have been used for up to a week. The smokey exhaust stops however after a few hours of running. I'm sure...

    Isolation Switch

    We have identical isolation switches on both our motors. They are the push-to-make type. When the cord is pulled off the button pops out and, theoretically, the engine cuts. This isn't always the case however.....any ideas?
