Questions & Answers

Is this a genuine original part?

Yes, this is an authentic Quicksilver product, which is the official parts and lubricants brand for Mercury Marine engines.

Can I mix this with the High Performance (Green) Gear Lube?

No. It is strongly recommended NOT to mix Quicksilver Premium Gear Lube with Quicksilver High Performance Gear Lube or any other lubricants, as this can affect the protective properties of the additive package.

How often should I change my gear oil?

It is recommended to check and replace gear oil after every 50 hours of saltwater use or at the end of every season before winter storage to prevent damage from potential water ingress.

Note: Always refer to your engine's owner manual to ensure you are using the correct oil viscosity and volume for your specific model. Available at 4boats.co.uk.

Winner of the aggressive chew competition
Color: No Stuffing Blue Eel
I bought several toys for an insane Jack Russell and this is the unlikely winner. It is a softer toy, but it is stitched together nicely and there are various components that distract the dog and keep him busy. First, it can be rolled up and stuck with small but strong Velcro patches, so it’s not just a sitting duck, the dog has to figure out how to unroll it which is fun. Next there are five little pockets on one side that you can put treats inside, which draw attention to the toy and give him another task. He did partially rip some of the flaps on the pockets in his zeal to get the treats. Then there is the squeaker, which he dispatched of in like 4 seconds (somehow without ripping the fabric(?)), then there are all sorts of crinkles and textures on both sides. All of this and the good stitching make it a toy he wants to play with but that he doesn’t annihilate in one day. The hard plastic toys are also good but I feel like I need to watch him carefully for fear that a sharp chunk will come off. The medium chew toys are cool but he’s just not into them. So this wins!

My dogs favorite toy!
Color: Blue & Yellow Eel Bundle
This is my Jack Chi and Yorkies favorite toys (it helps when they get 5 mini milk bones). It is a tough toy, but not impervious to a Jack Chi determination to remove all squeekiees! Squeekie or not, it's still their favorite toy for tug-a-war.

Fun Toy
Color: No Stuffing Blue Eel, Color: No Stuffing Blue Eel
My dog loves this toy. It has 2 squeaky & also has crinkly sound along with the slots for treats. However it is not very durable. The treat slots were pretty much destroyed with the first use. I'm still giving it a 4 star because it is so fun & entertaining for my GSD.

Kept puppy interested!... Till she chewed it apart in 5 minutes
Color: No Stuffing Blue Eel, Color: No Stuffing Blue Eel
I'll start off by saying this is a really unique toy. You really can hide treats in the pocket and the velcro is strong enough to roll it up that it won't come undone easily. The different textures and sounds interest my puppy! And she LOVES it! But it didn't last long with her. She LOVES rope toys and ripping them apart and eating it. I literally had just given it to her and not even a minute later (not joking), she had torn off a row of the rope-like part. 5 minutes later, the tail is already in shambles lol So long story short, great and interesting toy to keep the doggy from being bored. Maybe not so great for aggressive chewers/rippers in the long term. More than likely will be torn to shreds by the end of the day.

Great quality, fun design.
Color: No Stuffing Blue Eel
Wonderfully durable.. We have a 3 y/o australian kelpey and a 2 y/o pitty.. both are incredibly playful and tear up toys like nobody's business. A lot of the time under a day.. We're on day three with this eel, they love it and its holding firm (no tears or missing pieces). Squeakers are their favorite and these ones are perfect ( prominent but not too loud)
