What Frank said. Get a spare prop. The 25/27 LT's are rated for 9x7 but my 27 runs better with a 9x6, I am just above sea level so what conditions you run in, elevation, load, all are factors on selecting the best prop. I would recommend synthetic oil and grease. I would remove any foam pre-cleaner on the air filter. I would advance the throttle and set the motor to around 4200 rpm out of the water. Because you don't have gear reduction (excepting on the MB SLT- which is still very new) on the LT, additional rpm's have very limited gains.I tried running "hot" plugs but no real difference- just get standard ones like Champion or NKGD. The beauty of the LT is its simplicity. Depending on your hull, balance your weight. Make sure the cavitation plate is just under the water- bend the trailing edge of the plate (or "trim tab" supplied with some LT's) carefully 1/4" at a time, up or down, to get the best result. Gatorglide or Steelflex is suggested for the boat hull bottom. If you bought a used motor, check the shaft- if the there is excessive play at the prop end, change out the bearings and seals. Tighten all motor/frame nuts/bolts. Make sure your kill switch is working and wear that lanyard! No substitute for stick time! If you have not done so, change the oil/filter/plugs and do so at the recommended intervals. If there is no tiny tack, install one. Ok, enough said for now, all this is minimal cost so don't cuss at me!
