I need to drop the lower unit on my Nissan(Tohatsu) 9.8 to change out the water pump impeller and maybe other related parts. What bolt thread lock(er) do I use on the lower unit gear case bolts and water pump bolts to reassemble. The service manual says ThreeBond 1401 for both. I can't find 1401, though 1401C is available. 1401C has a higher torque value to break it free. My '90 4hp Johnson manual says OMC Lock for the lower unit bolts, but OMC gasket seal for the pump mounting bolts. All I can find on-line is Loctite Blue. Can't find any outboard motor branded lock compound. Frustrated in Boise! Thanks!
