"Last August I was lucky enoug
"Last August I was lucky enough to purchase my Grandmother's 1991 Larson All American 190BR 4.3L Mercruiser / Alpha I and trailer for $1000. The boat was a constant source of turmoil in my family, and consequently had really never been used. When I went to see it at Cal Marine in Door County, I was extremely pleased to see a time warp sitting in front of me. The engine hours read 64, and the condition could only be descibed as "brand new". I had them replace the impellors, and summerize it, and I enjoyed it for about 12 trips before returning it to Cal for the winter. My only complaint is speed. It runs flawlessly, but tops out at about 45mph, according to the speedo. I would like to break the 50mph barrier. How realistic is this? I would love any and all opinions within a reasonable budget. Is a supercharger available for this engine? Are trim tabs beneficial for this application? Any practical or performance "hop-up" suggestions would be greatly appreciated. The manuals say I have a #48 78120 A40 19P prop. Thanks in advance!"
