Water in the Lower Unit Keeps Coming Back - Seals and the Pressure Test Explained
Milky gear lube means water is getting past a seal, and changing the oil alone will not stop it. Learn where water gets in (prop shaft seals, driveshaft and shift shaft seals, drain and vent screw gaskets), how a pressure and vacuum test finds the leak, and when to do it yourself or hand it to a shop.
Water Inside the Outboard Cowling - Seals, Latches, Drains and Washing
Find out how water is getting under your outboard's cowl, from simple causes like a latch that isn't fully closed, blocked drain holes or the wrong washing technique to a worn cowl seal or a cooling leak, and fix it before salt corrodes the powerhead and electrical parts.
Where Is the Water in My Bilge Coming From? A Step-by-Step Leak Finder
Track down the source of water in your bilge, from the cheapest clues (when it appears, salt or fresh) to the usual suspects: rain and deck drains, the freshwater system, AC condensate, the shaft seal, raw-water hoses and through-hulls. Fix the leak instead of relying on the bilge pump.
