Blog How To Replace Gear OilHow To Replace Gear Oil

Author: Stuart Buckingham   Date Posted: 30 July 2020

Whether your outboard is 2 stroke or 4 stroke it will have a gearbox. The gearbox is the area of your outboard that the propeller is fitted to and, as the name suggests, a gearbox is where your outboards forward, neutral and reverse gears and bearings are located. Keeping these gears and bearings in tip-top condition requires lubrication. Marine gear oil is what is used and should be replaced every season. It is a pretty simple task, provided you have the right tools and take the correct steps to do the job... continue reading

If I were to ask you what the five most important things to check when servicing an outboard were most would rate a thermostat pretty low and some, in fact, wouldn’t even rate it. We are trained to think that the heart of the cooling system is the water pump and it should be checked and changed annually, and this is correct, but if the water pump is the heart of the cooling system then the thermostat should be considered the brain!... continue reading

You’re heading home from the boat ramp, it’s been your last outing for the season and soon the boat will be flushed, greased and stored away ready for the next boating season. But as you’re going through the storage process in your head you pass a gas station and the question you ask yourself every year jumps to mind, “Should I be filling the fuel tank up? Or should I be leaving it almost empty?” What to do?  This question has appeared on Forums, Facebook Groups and has been asked of Outboard Technicians since Noah strapped a two stroke on the Ark... continue reading

Author: Stuart Buckingham   Date Posted: 30 May 2018

The term 'blow a gasket' is certainly a widely used term in the Aussie vocabulary and almost as Australian as 'she'll be right' or 'stone the crows' but unfortunately, for those of us in the boating scene, unless you're hearing about a mates reaction to losing a big fish it probably means you're outboard is in strife and needs a new head gasket and possibly more... continue reading

Your outboards water pump is its main cooling mechanism, without it your engine would overheat in seconds leaving you bobbing around the ocean like a randomly positioned FAD. If you're someone who doesn't mind getting out the paddles on the odd occasion and getting a bit of exercise then perhaps this blog isn't for you but, if the idea of a 3km paddle back to the boat ramp isn't your thing, then please read on and see why inspecting your water pump is so important... continue reading

They say a bad tradesman always blames his tools however, you can only blame yourself if you don't have the right tools! Working on outboards can be challenging at the best of times and these challenges can be amplified if you don't have the right tools for the job. Below are a few of the tools I believe are a must have, for any marine technician working on customer outboards or the DIY'er working on their own or their mate's outboards... continue reading

 

Blog Tips For Buying A Used OutboardTips for Buying a used outboard

Author: Stuart Buckingham   Date Posted: 28 February 2018

One of the biggest misconceptions that people have is that an outboard with good compression on the block is in excellent order. This is only a partial truth. An outboard does not only consist of the engine block, a damaged gearbox or trim and tilt unit can be an expensive exercise to repair or replace and can quite easily cost you thousands of dollars... continue reading

But, the wrong propeller on your outboard can cause under performance in the way of a lack of top-end speed, hole shot or could possibly cause excessive load on your outboard resulting in powerhead failure... continue reading

Blog How to flush your outboardHow to flush your outboard and why it's so important

Author: Stuart Buckingham   Date Posted: 22 May 2017

One of the biggest killers of the modern outboard is corrosion and often it's not what you see, but rather what you don't see that causes the biggest problems. Outboards are raw water cooled and draw water directly from their environment to cool down. In fresh water, this is not a problem but in saltwater, it opens the engine up to salt build up and corrosion within the outboards internal cooling passages... continue reading

1997 4 stroke 9.9hp

23 September 2023
I have a 1997 9.9 hp 4 stroke and I have a couple problems, first is it’s really hard to cold start, I will try in the morning and I can’t get it to fire but 30-45 mins later and she will fire right up and once I do get it fired up at full throttle it will die but fire back up on first key turn and then 30 mins after all that she will run fine fires right up and doesn’t die at full throttle, any help would be appreciated greatly

Outboard Spares Response
Hi there, I would suggest taking the carby off and overhauling it whilst seeing if there is any contaminants in there making sure to thoroughly clean all jets. Refit and tune. Then see if the problem still exists. Cheers.

2004 Mercury two stroke carbureted engine

By: on 20 January 2021
Had carbs disassembled and flushed/cleaned. Reinstalled and engine ran good. Went out fishing and all seemed good on that trip. Took it out a few days later for a wot test for approximately thirty seconds, ran good. Was not aggressive with throttle advance not wanting to cause unnecessary stress. Reduced power settings to three thousand rpm and came back into the dock area and went into idle setting for taxi to my slip. Engine started idling rough and remained rough into the slip. Engine died on it’s own. Hard to restart, but ran ok above twelve hundred rpm. In idle, very rough still. Died on it’s own. Started it today, started fine but rough, ok above approx twelve hundred rpm. Could I have created a pre ignition condition during the brief wot test and burned a piston? Filters were replaced back in mid November prior to the Carb work. I’m in San Carlos Son Mexico. Thank you.

Outboard Spares Response
Hi, Hmm, I doubt you have burnt a piston but check the compression first and see how you go. I would think it is a stator issue by the way you have described it. I'd be checking the stator output and seeing if it is within spec. Good Luck!

1992 yamaha 150 pro V oil leak

By: on 13 April 2019
started motor first time this season, would not stay running, walked to back of boat and saw oil pouring from casing. oil is coming out of bottom two carbs, sounds like oil pump constantly running even with out motor running just key on,

Outboard Spares Response
Hi, sounds to me like the joint link on the end of the oil pump rod (between the carbies and the oil pump) has cracked and split. When this happens the oil pump advances the consumption to max (it does this as a safety precaution rather than having the pump deliver less oil than required and have the engine run lean on oil) and causes over oiling. Simple fix with about a $10 part, assuming I am correct. Cheers

1997 25hp mariner 2 stroke problems

24 February 2019
I have a 25hp mariner 2 stroke while running I had a wire get nicked going from the the Cdi box to the stator by the flywheel which shorted and caused me to have no spark.I replaced to the coil pack and the stator and got my spark back and it cranks right up now but now it won’t run full throttle it’s like it’s missing are choking down under a load. Any advice would be appreciated?

Outboard Spares Response
Hi, Thanks for getting in touch. From what you have said there is a chance that the switch-box may have been compromised when the stator wire was damaged. This is because the flywheel would have created a short-to-ground which may have damaged the switchbox. If you can get your hands on another switchbox I'd be looking down this path. I hope this helps. Cheers
