Jenner}4/JH.10.7.40. B.80 Marine Unit. We send you herewith the last of the designs for the installation of the inter-cooler. The whole of the work is now finished. Herewith PL.198 Fresh & Salt Water Connections and oil fittings. PL.282 Inter-cooler and Header tank. We have carried the inter-cooler from the bracket off the front of the wheelcase. We forsee that it may be necessary to introduce a tie somewhere near the top of the header tank if vibration is too much for this mass. It is worth a trial without a tie as it is steadied to some extent by the larger connections. We are a little at a loss to know who decided on the size of the Harrison inter-cooler type HE.114-205. It appears to be on the small side for 150 H.P. Oy. quotes a figure of 40 B.T.U's. x 150 = 6000 B.T.U's. The sample inter-cooler is the smallest size and it is used on the Gray 100 - 150 H.P. engine.
