Whaler Central - Boston Whaler Boat Information and Photos

While I can probably troubleshoot this, I thought I would seek your advice to save time and also contribute to the knowledge base.

Boat - 1991 Outrage 17 with internal 32 gallon tank
Engine - 2003 Yamaha 115 4-stroke

Background:

I replaced the entire fuel-water separator, primer bulb and fuel line to the engine. I also drained the fuel filter on the engine and installed a new filter. There is no gas in any of the fuel line or filters.

Rigging:

Tank line goes ~5 ft to separator then primer bulb then ~5' to engine filter under the cowl.

Questions:

What is the best way to prime the filters and line?
Will the primer bulb have enough "draw"?
How do I get the air out?

While I have ideas, I would be interested in yours.

I just started fresh with my engine. New Yamaha 100HP engine (new to the boat) all new fuel lines, new screw on Yamaha filter, new primer bulb. It took about 15 pumps on th bulb, but the filter finally filled up. Cranked right over as soon as fuel got to the carbs.

Guess everyone has their own method but I like to fill the fuel/water separator with gas and disconnect the fuel line from the engine and then squeeze the primer bulb/fuel line into the gas tank until there is a good stream. Then just connect the fuel line to the engine and let the fuel pump do its job. This method works well for me.

Thanks guys,

I was thinking the same things, just was not sure, given the distance of the pickup and small pull of the bulb whether it would work. Think I will fill the fuel water separator, disconnect the fuel line at the filter and give it a go.

While on the surface it appears straight forward, thinking about it made it sound more complex than it should be. It's easier to give others advice then to figure out my projects! :p

When you begin priming, make sure the primer bulb is vertical with the arrow pointing straight up. I fact it works better if it is in that same position all the time.

Success! Just like you guys said. Took a lot of pumping but worked like a charm. Better yet, no leaks.

With this project completed, I found a new project that is challenging ...frozen cover screws on 704 control. will start a new thread.
