Hello fellow boat buffs!! This is my first post on iBoats and I hope I can get some answers. I recently completed a total restoration on a 1986 Bayliner Capri bowrider 1950. It has the Aq131 with the 275 Penta our drive. I have replaced the stringers, transom, floor and reupholster the entire boat. I also had that engine completely rebuilt with new pistons, new bearings, and all new seals. I have replaced all the bushings and O-rings in the outdrive and also replace the raw water pump and heat exchanger and exhaust manifold...and that problematic water neck and seal. I put a clear hose on the suction side and out on the lake I don’t see any bubbles. The engine runs about 170° or at wide-open about 175°. The problem that I am experiencing is that the exhaust manifold gets hot. It is brand new and I’ve been shooting it with an infrared temp gun and it’s about 200°. Besides that hot manifold problem everything else is great. With three people on board I can get 35 mph out of this little motor! So hopefully someone can let me know if the hot exhaust manifold is normal or if I should be concerned?
