over the next few days i will document a auxillary wash down pump install on a 20' alumaweld. will be including all pics and stages of installation.


all parts needed to do install, all tools, and pictures of the final product



those people that have larger boats that have multi uses, in my opinion, this is next rod holders in its importance.. as it makes clean up so much easier once done for the day...


keep an eye on this thread as it will be updated nightly

and for those wondering, this is an ABYC standard installation, so no short cuts here.

STEP 1:


TAKE INVENTORY!!!

make sure you have all tools, pieces and kit components BEFORE you start. this will save time and hasle and money later.

Step 2:

once everything is accounted for and layed out in a organized fasion remove, open or set asside any compartments that block access to inside of transom assembly to decide where the through hull below waterline will reside.

as this picture shows this boat has a carpeted wall covering up the rigging under the splash well... so this all needs to come out

once removed we have a view of the transom

our hole will be placed in the void space between the oil tank and the lower engine bolt hole seen in center of the pic

using a pilot drill bit drill if possible from inside out then use 1" hole saw to make hole for through hull fitting below waterline this particular install required measuring the center of the void area from the drain plug and drilling blind from the outside.... not ideal but after measuring about 7 times it worked out

at this stage you are at the point of no return. you now have a hole in the boat... so onward and upwards... choose a fairly hidden yet fully accessable location to install the pump and filter assembly, in this case it will be on the starboard side behind the wall but reachable from the access for the battery switch. thus allowing cleanout if needed.


pump mounts to floor or bracket using the 4 # 12 2" long screws. the screws go through a vibration resistant mount to quiiet the operation.

I attached the lines on the pump for visual reference to varify no kinking of hose notice no clamps yet just slid on

now I placed the holes for the switch and the discharge hose hook up... I placed the hose discharge in the Splashwell to ensure that if the pump or switch fails with the hose disconnected and the pumps begins to operate the hull wont fill with water and sink, i have seen that happen before. so think about where you mount your hose hook up so its safe if you ever had to moore the boat for a season as this boat is durring spring and summer.

if you notice the cut out for the switch is rounded on the top, this is because the wires will be ran this way and that ensures that the wires wont contact sharp aluminum and cause a short over time.. also the fuse has been removed form this switch panel because the boat has a main breaker fuse panel under the dash and no need for a secondary protection in this application.

mount the discharge and swith panel with the #8 and #10 screws respectivly and now you can go back to installing the through hull, hoses and clamps that all will be recieving a coating of 3m5200 as a sealer in addition to the clamps and backing nut to ensure water tight seals on any fitting below the waterline.


this is where i got rained out so will continue the thread after tomarrows day at work.

Not to worry, you have inspired me to get to work and replace my washdown pump. Luckly I just need to do a swap out. The boat is 21 years old and those pumps don't last forever in the salt. Here is a picture of my washdown system I used to get through the last season. It's the round white thing with a handle. The new pump sure will be nice to have.

that system worked on this boat for 20 years... but the customer felt it was time to enter the world of extra gagets since the boat was stripped and re rigged last year and the switch panel has a few new extra spots it didn't used to have.... not shown, but seen on my website was the fact it also added hydraulic steering, 10" setback, new prop, raised engine, new kicker... ect...


for a couple hundred bucks it is a lot easier to keep the boat cleaner especially in the cold winter and spring water months as hands dont get wet.... and this boat also gets used for water sports and muddy beaches seem to be normal... so adding in ability to sprey down deck will keep things cooler and cleaner:)

I completely agree. I picked up a Shurflo washdown kit to replace my fried pump. Up at lake Simitutus on a hot day it provides a quick way to cool down while fishing!

ever seen a black aluminum boat in 100 degree water skiing weather......

saving the potential for 3rd degree burns is worth the $$$$ itself...
