We are sure you have noticed by now that we have replaced most of the hose clamps on the 6.2L Ford based engines with single use Oetiker clamps.

The new clamps, when properly installed, provide an even clamping force around the hose and a much more secure connection that reduces leaks and the possibility of hoses blowing off. In locations where the hose may have to be removed to facilitate draining/winterization, we have continued to install conventional worm gear style hose clamps.
 
If you do have to remove an Oetiker clamp to replace a hose or other component, the required procedure is to use an Oetiker clamp to complete the repair. If you use a conventional hose clamp instead of an Oetiker clamp you are accepting the responsibility of the security of that connection. If the hose leaks or blows off the fitting after the repair, the responsibility is yours and warranty will be disallowed.
 
To make it more convenient, Indmar has made service packs containing 10 each of the various size Oetiker clamps used on our engines. The service kits are as follows:

• 5/16” ID Hose P/N 735040-10
• 5/8” ID Hose P/N 735026-10
• 3/4” ID Hose P/N 735041-10
• 1” ID Hose P/N 735037-10
• 1-1/4" ID Hose P/N 735038-10
• 1-1/2” ID Hose P/N 735039-10
• 3” ID Hose P/N 735042-10
• 3-1/2” ID Hose P/N 735043-10

Oetiker Clamp Tool P/N 997350 (Oetiker 1410083 Side-Jaw Ear Clamp Pincers also available through Amazon.com or other on-line outlets.)
 
Note: The Oetiker clamp sizes are valid only when original equipment Indmar hoses are used. Hoses from another manufacturer may not have the same wall thickness or material as Indmar hoses and the clamping pressure provided by the Oetiker clamp may not be appropriate.

The new Raptor Engines has some requirements that deviate from the recommendations that we have made for a number of years. The Naturally aspirated Raptor models require the use of approximately 8 quarts of API SN synthetic blend 5W30 motor oil. The supercharged models require approximately 8 quarts of API SN fully synthetic 15W50 motor oil.
​
The 2017 model Raptor engines use cartridge style oil filter instead of the previous spin-on filters. No more stuck oil filters! You should drain the oil from the engine before removing the filter so the oil drains from the filter canister and reduces the possibility of making a mess. The new filter comes with a replacement O-ring for the filter cap that should be changed when the filter is changed. The torque for the filter cap is 18.8 foot pounds (25.5 Newton Meters). Don’t overtighten.

WHAT YOU SHOULD DO.

During dealer preparation of a new boat, or when the customer brings the boat in for maintenance or repair services, install the new raw water inlet tube assembly (P/N 495934)  to reduce the possibility of the raw water inlet hose blowing off and to simplify draining of the system. 

Parts Required:
​Raw Water Tube Replacement Kit P/N 495934
 
Special Tool Required:
Oetiker 1410083 Side-Jaw Ear Clamp Pincers. Indmar P/N 997350. Also available through Amazon.com.
 
Procedure:
Use a side cutting pliers and cut the Oetiker clamp securing the hose to the supercharger heat exchanger.
 
Loosen the hose clamp securing the hose to outlet side of the raw water pump.
 
Remove the hoses and tube from the engine as an assembly. Discard.
 

​Place the Oetiker clamps from the 495934 kit over the ends of the hoses of the tube assembly.
 
Install the tube assembly on the outlet fitting of the supercharger heat exchanger and the inlet fitting of the raw water pump.
 
Position the Oetiker clamps within ¼” of the cut ends of the hoses. Secure the Oetiker clamps with the Oetiker Clamp Pincers. NOTE: The use of Oetiker clamps is required. Dealership assumes all liability if a hose blows off and Oetiker clamps were not used.

WHAT IS THE STRAINER PRO?

• The first sea strainer with a built-in flush kit system
• Extends the life expectancy of inboard marine engines, cleans the entire raw water-cooling circuit, adds protection when operating in lakes with heavy vegetation and simplifies aquatic invasive species (AIS) flushing
• Available to boat builders and to consumers as an aftermarket part. Consumer's must purchase the part from an authorized Indmar Dealership
• The Strainer Pro works with and can be installed easily on any inboard marine engine

HOW DOES IT WORK? 
Let’s take a look at the design and how the Strainer Pro works

​The Strainer Pro’s space saving design optimizes flow dynamics and since there is one integrated unit instead of two, there are fewer potential leak points.  Indmar also added an integrated O-ring to improve sealing capabilities and the units straight axial flow design enables water to flow more freely straight through the strainer and reduces flow loss which provides more water to be utilized by the engines cooling system.

At the manufacturer level, Indmar’s boat building partners have been able to eliminate parts, which reduces the part numbers that have to be budgeted for, bought and stocked.  Their OEM’s have also been able to reduce labor cost for installation.  And for the consumer, at aftermarket level, the Strainer Pro has proven to be easier to install (time-savings) and consumers save additional money since they only have to purchase one part instead of two.
