Integrated Bow sac install without drilling-205

Like a lot of people with DD boats, I'm looking at ways to get my boat ('97 205) weighted without excessive sacs everywhere. The integrated bow sac looks like a good solution to hidden ballast even if the space limits full weight (read estimated 400 lbs?). The link below looks like an easy install option but I wanted to see what others thought. I could probably link the vent line with bilge vent with a check-valve or I could just self vent the sac when filling. I'm trying to follow the KISS principle with this project.

In addition to bow sac, I'm considering lead weight (520# pop bags) for under rear seat and in-floor cooler and possibly upfront as well.

Am I trying to fit a square peg in a round hole? Should I just stick to sacs on the floor?

Any thoughts would be appreciated. Thanks!
Nick

Any shut off valve below the water line should be brass. I have read that it is a coast guard regulation as well.

I'm gonna be a bit direct with this one. Pulling water off the rawr water line, cooling system, is just a bad, bad idea. Why would anyone think that compromising the cooling system would be a good idea, hell even an idea in the first place.

I would strongly suggest you look at other ideas. I know you said you don't want to drill, but it's not that scary of thing to do.

Follow the instructions at Wakemakers and you'll be fine.

i have a rear seat sac that goes in back. it fits with the seat down but has a little more capacity with the rear seat up in the sundeck position. i will be installing a 750 pound sac on the left side of the engine box over the winter to give me a surf wake. up front i thought about the integrated bow sac but it ends up so far forward that i thought it limited capacity quite a bit. so instead i put 2 side sacs up front under the bow cushions and let them sit as far to the rear as possible to get as much water in them as possible.
with 4 or 5 people in the boat there is still plenty of room and it is definitely sitting pretty low in the water. it throws a beautiful wakeboarding wake, wont know until next year what kind of surf wake i'll have.

Thanks for the replies.

CR-
I'm no engineer but I would imagine that running a 1" hose from a "T"d off section of the raw water pump for a few minutes wouldn't change the engine temperature dramatically. If I had the tools for the thru-hull installation I'd feel a little more compelled but I don't.

TC-
Do they side sacs get pretty full under the seats? I agree the wake is great (at least for my needs) but just don't want the hassle of throwing pumps over the edge or taking up space if possible. I guess the next step is finding fat friends.

They fill up just about all the way. if people are sitting up front the bags will pick them up.
i used 2 jabsco ballast puppy pumps and put to intakes through the hull, one for each pump. i added 2 vents through the hull for overflow.
i know drilling holes in your boat sounds scary but it's well worth it and much better than hanging pumps and hoses off the side. i can just add or remove water from the front or rear to shape the wake or compensate for people.

I'm not either which is why I would not risk it.

For the through hulls all you need is a cheap $4 hole saw and any drill, some masking tape, the fittings.

and the nerve to put a big hole saw to the bottom of your boat

use plenty of 3m sealant and you'll be fine.
