    Tightening hose clamps

    Don’t know how often you guys tighten your hose clamps on your engines, but if you don’t at least check them every 6 months you might be sorry. I did mine about a year ago and was running this weekend and saw a water leak above the transmission, so after we stopped I tried tightening the hose clamps in that area and one was very loose and broke as I was tightening it, so I replaced it and no further leak. When I got back home I checked all my clamps and quite a few needed at least a quarter of a turn tightening, a couple needed even more. That is now on my 6 month check list. I quest vibration slowly causes loosening. John

    I normally do mine once a season and I do find some have loosened. I’ll add it in every 6 months now. Thanks for the heads up John.

    Re: Tightening hose clamps

    Something that works for me. Even the best clamps start rusting when they're clamped onto salty hoses. For all hoses, I paint the hose and the clamps with phosphoric acid. I'm trying to neutralize, or at least temporarily so, the rust. Seems to work. So, don't just tighten them. Loosen and rotate them around to look at the undersides or the inside for signs. Any clamp with more than surface corrosion get tossed.

    I've steadily been upgrading to T-bolt clamps over the years where applicable, BTW.

    In the smaller sizes heavy duty “316” stainless clamps without the holes in them offer better corrosion resistance and stay tighter as the hose material can’t deform through the holes as is possible with standard hose clamps. https://www.westmarine.com/buy/aba-o...2?recordNum=29
