Mercruiser 4.3L Longblock Replacement Options
TOPIC: Mercruiser 4.3L Longblock Replacement and Horsepower Upgrade Options
QUESTION: I have a 1997 rinker captiva 192. Merc # K170XXX. The block cracked over the winter. I am looking to replace the stock 2 barrel carb motor with hopefully a upgraded 4.3. I don’t want to go radical but justa increase in performance. Pricing is critical. I am looking for a long block. So what do you recommend. I do not want to have to modify anything in the boat. Thanks, Scott
RESPONSE: There are a couple of options you could potentially go with and using the links below you can review these options. The 1st option listed below is the remanufactured Vortec 4.3L longblock. This product includes a 24 month warranty and comes without tin ware (oil pan, valve covers, timing chain cover, etc) but does include a full gasket set as is needed with the re-assembly. The second option is the New version of the Vortec 4.3L longblock. As illustrated in the picture this option does include the tin ware. The new longblocks carry a 12 month warranty. The third option is the Power Package which includes a new Vortec 4.3L longblock along with a 4 barrel carburetor as well as the complete ignition system. If you are currently running the standard 2 barrel carbureted version this is a great upgrade option to give you a little more top end horsepower. The fourth and final option is the 262 HP longblock. This is a balanced and blueprinted 4.3L longblock that produces 262 Hp and 300 Ft-Lb of torque. This upgraded performance option will require an upgraded fuel & ignition system to support the requirements of the additional performance.
