After being given a totally absurd quote for my 10hr service I decided to do it myself, complete success and so easy, so here's my experience with me completeing my 50hr service. A large part of the service is "check", I'd imagine the dealers charges are high because of the time it takes to check all the areas but being the owner your in the best position to know what does or does not work.
Complete service kit compliments of Jet boat pilot, $217.
First off I got the engines nice and hot, great shooting around on my own, I really got to feel how the boat handled with no weight on board. My oil extractor was purchased from West Marine but is exactly the same as the models sold on Amazon and alike, if I remember right around $90.
With the oil nice and hot and not rushing the extraction I managed to withdraw nearly the full 4ltrs (3.5 qt), puppy pads are a must, especially with taking the oil filter off.
Next was the removal of the oil filter, my particular wrench was also purchased from West marine and is the small size. This wrench is a breeze to use, no damage to the filter and with the easy access on our boats is ideal.
Installing the new filter, make sure you lube the rubber seal so it tightens fully by hand plus add a little oil to the cartridge just so the engine runs for a minimal time with no oil pressure on first start up.
Notice where the filters are manufactured? Maybe Geoff Copper can get us a deal .
Refilling the engine with oil I replicated the amount I'd withdrawn, around 3.5qt, just under 4ltr.
Next I checked the air filter, no replacement at 50hrs. Very clean as I'd expected but was surprised to see the factory had held the filter in place with a screw.
Next up the spark plugs, which I believe have conflicting info whether they get changed at 50 hours, my manual says yes but since my boat was a year old I'd change them anyhow. Once the plastic cam cover was removed it revealed the four coil packs which are removed by the two 10mm bolts on each. After withdrawing the plug cap you'll need a long reach socket for the plugs. I purchased NGK LFR6A, there is an alternative with -11 at the end of the plug number but these are not correct for the 1800 engine. The plugs come with the correct gap but it doesn't hurt to check, plug gap us 0.8-0.9 (0.031-0.035).
Now we come to greasing the intermediate bearing, such conflicting info on this and so much speculation, with my findings I hope to dismiss any myths.
My 2016 manual says at 10 hrs the bearing should have 33.0-35.0cc (1.11-1.18oz) which with my small grease gun I worked out to be 25 pumps. Now at every 50hrs or 12 months the bearing needs 6.0-8.0cc (0.20-0.27oz), this is confusing as cc is volume and oz is weight. My conclusion was both measures work out to a teaspoon and because I'm British I like tea
, this teaspoon measure is 10 pumps with my small gun so that's what I put in and what I'll put in every 50 hrs or 12 months.
You can see just underneath my bearing carrier the excess grease that has been expelled from the last 40hrs of use, this is common and not detrimental. I used Quicksilver grease and the gun was also purchased from West Marine however I acquired the flexy pipe from an auto shop as the ridged pipe included did not fit in the space avaliable.
Finishing off the service now is really just checking over all the systems and components, the full check list is in the manual. Greasing everything that's moves is my motto with particularly attention to the steering and bucket shift cable and linkages.
Don't forget throttle cable and I like to grease my clean out plugs, some may differ and some may say no, the choice is yours.
And finally because I boat in salt water I like cover everything with Boe Shield.
I'm not a marine engineer but have an automotive background and this guide is just that, I've uploaded what I did for my 50hr service and hope its of some use to somebody.

, never really gave the bilge screen any thought, and theres my argument with self-service. I doubt very much a dealer would check it and any time it kicks in I take a quick look at whats coming out, if it was weak I'd assume there's a blockage so I would then clean/check it.
