well it's been a very busy drinking some

shrimp okay is a lot of dancing one

point they even got up on the tables but

most importantly out of all that I got

to meet some chickens so pretty good

month for me today was going to be a

woodworking David is pretty contrarian

so it said it is engine maintenance day

turns out I've been doing this separate

wrong interval but it's okay I need to

change the oil change the oil filter and

I also probably should go ahead and

change the fuel filter because that one

it's been a year already

so we'll probably go ahead and knock all

that out today so I've got to record

filters that need to be whole different

types those are pretty easy to do I

should probably also check out this one

[Music]

may the process for this is going to be

pretty easy what I do is I get the

engine nice and hot because we're going

to do the oil first then I shove a tube

down the dipstick hole and suck the oil

out because on the boat you can't really

pull it up and you know get under there

with a drain plug so once that is done

I'll put the new oil in through the oil

filler cap over there I should probably

also clean the air filter while I'm down

here

the gearbox oil probably could use a

change but I don't even know what kind

of oil it takes so we're gonna have to

look into that and then yeah should be a

busy day

is it weekend really I'll probably have

to finish most of it tomorrow am i will

get my pile of filters we're ready to go

well I've got the engine running I'm

gonna go ahead and label my filters I'd

like to put the date in the engine hours

on them that

some easy reference to when it was last

change right so I've got the oil flowing

into the chamber here just give it a

pump every now and then to keep it

flowing it'll start sucking air once

it's finished thing about these is that

they're self-contained

area topped it off

well that I pulled out just a few

seconds ago so I'm gonna take it over to

the oil pump station and empty it out

and come back and finish it off we are

sucking out the second tank right now

and once that's finished we'll go from

there and put the new stuff in right got

a strap wrench on last time this was

completely frozen when she broke free

lunches really suggestion of people who

are learning mean I'm using a plastic

bags got catch

[Music]

okay all right

we are topped off with a little and

gonna clean up in turn and we'll run in

and fur bed to double check it check

everything oil change that bad now and a

half total cost about $70 as well with

the filters in the well itself I think

that's why people think that voting is

expensive because they have in their

mind oh I've got to change the oil and

change the filters all the time but

sailboats you know on a motorboat yeah

yeah you're gonna do that every month

and it's gonna cost you an arm line

an arm and a leg

but honestly sailboat is not too big a

deal just like learning guitar really

all right I've got the alternating

current turned off to here because I

want to catch a little bit of diesel

[Music]

[Music]

those air bubbles can lead to bad things

that one and I want to see what the

inside there's the other one new filter

needs to actually be topped off with

diesel fuel and I've got a little cup

here of excess diesel so I'm gonna fill

it up and top it off no put it in there

but uh the reason you want to top it off

now that you got is that whatever fluid

level is in here that's how much of the

filter you're actually gonna be using so

if you have a full full filter it'll be

using the entire filter surface if you

have an air fuel level somewhere in here

then it's only gonna use the lower half

of that filter so you want to use all of

the filter otherwise you're gonna have a

lot of problems down the road

[Music]

alright the fuel system has been bled

off as per the instructions there's a

toll on the battery quite a lot to the

battery so I want to try to run the

engine now for a couple minutes just to

recharge the batteries and make sure

that everything is hunky-dory crank her

up

[Music]

and it didn't water run let's try it

again

[Music]

a little bit more fuel

nope still nothing

all right we can go back and try it

again try purging it about four or five

times I gotta go watch the Super Bowl

now so I'm gonna have to come back a

couple of theories one that people I put

in little theories might have been bad

now I just gotta flush that out you I

might have a clogged injector I don't

want to replace them anyway yeah that's

a project for next week hello

all right fourth time is the charm

finally after many many sleepless nights

I've got the fuel system purged we're

gonna go check it out down below

like to thank the good people have read

it for helping diagnose that issue

fourth time is the charm as it turns out

these Perkins as a other people have

stated are very very touchy about air in

the fuel system so apparently it's not

uncommon to take four or five times to

purge it correctly so apparently all I

needed was one more we're good thank you
